【期刊论文】Tunable Semiconductor Microspheres ZnSe Semiconductor Hollow Microspheres**

Colloidal microspheres have been of continuous research interest ever since the beginning of the 20th century.[1-3] Traditionally, these systems have been regarded as ideal theoretical and practical objects of research because their intrinsic properties might be finely tuned by simply changing parameters, such as the diameter, the chemical composition, the bulk structure, and the crystallinity.[1-2] Recently, monodispersed silica and some polymer microspheres (e.g., polystyrene and poly(methyl methacrylate) have been employed as fundamental building blocks in the fabrication of photonic bandgap (PBG) crystals,[3-7] 3D macroporous materials[8, 9] and 3D crystalline arrays as optical sensors.[10] Although recent progress in this field has mostly concentrated on their potential optical application, the employed microspheres themselves do not exhibit any particularly interesting optical, nonlinear optical or electro-optical functionality.[3] To introduce particular optical properties into these systems, semiconductors[11] or metals[12] have been incorporated into silica or polymer colloids during the synthetic step, or coated onto polymer sphere templates to prepare TiO2, SnO2,[13] and ZnS[14] hollow spheres or core-shell structures.[15] However, until now, a simple template-free method to prepare semiconductor microspheres with intrinsic optical properties is much needed

【期刊论文】Silicate Nanotubes Thermally Stable Silicate Nanotubes**
李亚栋, Xun Wang, Jing Zhuang, Jun Chen, Kebin Zhou, and Yadong Li*

For many years, intense research has focused on new types of silicates with tunable pore sizes because of their great potentials in many areas, such as selective catalysis, molecular sieves, and gas adsorption and separation.[1-9] Zeolites with pore diameters of 3-10 " (roughly the same size as small molecules)[1-2] have found wide industrial application, however their relatively small pore sizes deny access to large molecular and/or bulky reactants and thus limit their further use in fine chemical and pharmaceutical industries. Recent progress in solving this problem has been made through the development of mesoporous silica[3-6] and non-silica[7-9] materials (MCM-41, etc) with pore diameters in the order of nanometers, however, compared with zeolites, mesoporous materials usually suffer from poor thermal and/or hydrothermal stability due to the amorphous nature of theshows the XRD patterns of copper and magnesium silicates. All of the reflection patterns in Figure 1a can be readily indexed to that of a pure hexagonal phase of Mg3Si2O5(OH)4 with lattice constants a=5.33 and c=7.269 "(JCPDS no. 82-1838) while the main peaks centered at 2q=20.04, 30.61, 36.07, 56.17, and 62.158 in Figure 1c can be indexed to the CuSiO3•2H2O phase (JCPDS no. 11-0322). The apparent broadening of these peaks indicates the small crystal sizes of the obtained nanotubes. Other silicates have been characterized by means of XRD and all the information indicates that as-obtained silicate nanotubes usually have distinctive clay-type structures with silicon to oxygen ratios of 1:2.5 within the layers.[10-11] Due to the excellent ion-exchange characteristics of layered silicates, cations residing between the layers can be further replaced, which make these nanotubes ideal candidates as molecular sieves.

【期刊论文】Selected-Control Hydrothermal Synthesis of α-and β-MnO2 Single Crystal Nanowires

The many polymorphic forms of manganese dioxide, such as α-, β-, γ-, and ä-type, have distinctive properties and now are widely used as catalysts, ion-sieves, and especially as electrode materials in Li/MnO2 batteries.1-3 As the operating properties of a Lithium battery depend not only on the manganese oxidation state but also on the MnO2 structure type, great effort has been made to prepare bulky or nanocrystalline MnO2 with different structures.1-6 However, to the best of our knowledge, the synthesis of a onedimensional (1D) single-crystal nanostructure of MnO2 with different crystallographic structures has not been reported to date, which may provide the possibility of detecting the theoretical operating limits of a Lithium battery as the 1D systems are the smallest dimension structures for efficient transport of electrons,7,8 and may give an ideal host material for the insertion and extraction of Lithium ions. Herein we report the synthesis of a MnO2 1D nanostructure: R-MnO2 with diameters of 5-20nm and lengths ranging between 5 and 10ím, and â-MnO2 with diameters of 40-100 nm and lengths ranging between 2.5 and 4.0μm.

【期刊论文】Synthesis and Characterization of Lanthanide Hydroxide Single-Crystal Nanowires**
李亚栋, Xun Wang and Yadong Li*
Angew. Chem. Int. Ed. 2002, 41, No.24,-0001,():
-1年11月30日
Nanowires represent a class of quasi-one-dimensional materials, in which carrier motion is restricted in two directions so that they usually exhibit significant photochemical, photophysical, and electron-transport properties which differ from that of bulk or nanoparticle materials.[1-11] In the last decade, many important materials have been prepared in the form of nanorods or nanowires to generate some unexpected properties[2-5] based on which, many new potential applications have been explored.F or example, wellcontrolled and monodisperse CdSe nanorods can be used in solar cells,[2] and can form liquid-crystal phases with orientational order and positional disorder in organic solvents; [3] single-crystalline, well-defined ZnO nanowires can serve as natural resonance cavities, and well-aligned ZnO nanowire arrays may serve as room-temperature ultraviolet nanolasers.[4] Along with chemical composition and crystal structure, shape and dimensionality are now regarded as particularly important factors that influence the chemical and/or physical properties of materials.

【期刊论文】Inorganic Fullerene Nanoparticles Fullerene-Like Rare-Earth Nanoparticles**
李亚栋, Xun Wang and Yadong Li*
Angew. Chem. Int. Ed. 2003, 42, 3497-3500,-0001,():
-1年11月30日
The landmark discovery of the fullerenes[1] has led to the development of thermodynamically stable forms of carbon whose dimensions are reduced to the nanoscale.[1-2] As an analogue to these novel structures, the concept of inorganic fullerene-like (IF) nanostructures has been initially described and confirmed by Tenne and co-workers.[3-6] Stimulated by the novel properties of fullerenes,[7-8] these IF nanoparticles can be expected to open new avenues in the solid-state chemistry of inorganic compounds and offer new opportunities for the application of such nanostructures in the emerging field of nanotechnology, as well as in numerous other areas.[9-12] However, up to now, only a limited number of IF nanoparticles have been successfully prepared from their corresponding layered inorganic compounds, such as WS2,[3] MoS2,[5] NiCl2, [6] CdCl2,[13] Tl2O,[14] NbS2,[15] and ReS2.[16] Thesynthesis of novel IF nanoparticles remains as a challenging task for the years to come. Herein we report the synthesis of rare-earth fluoride and hydroxide IF nanoparticles using a low-temperature hydrothermal synthetic procedure.

【期刊论文】From Surfactant-Inorganic Mesostructures to Tungsten Nanowires**
李亚栋, Yadong Li, * Xiaolin Li, Zhao-Xiang Deng, Beichuan Zhou, Shoushan Fan, Junwei Wang, and Xiaoming Sun
Angew. Chem. Int. Ed. 2002, 41, No.2,-0001,():

Surfactant±inorganic mesostructured composite materials[1-3] have attracted great interest over the past decade due to their potential applications as catalysts, separation membranes, chemical sensors, and in solid-electrolyte and optoelectronic devices.[3-8] However, to obtain these highlyor-dered mesoporous materials, removal of the surfactant species from the mesostructured composites is critical. Here we report on a simple and versatile vacuum-controlled pyrolysis procedure for the removal of the surfactant species from lamellar mesostructured composites of tungsten oxide with cetyltrimethylammonium surfactant cations (WO-L). In this process, pyrolysis and carbothermal reaction of WO-L take place in vacuo at 500-850℃, and bulk quantities of uniform metallic tungsten nanowires with diameters of 20±80nm and lengths ranging from 5 to 30m are obtained.We believe that raising the processing temperature induces curvature in the lamellar structure of the thermallyunstab le inorganic-surfactant precursor and finallyleads to the formation of tubular structures. The inorganic-surfactant precursor mayact as a template, which confines the carbothermal reaction and results in tungsten nanowires. This mayrepresent a universal approach for the synthesis of nanowires of other transition metals, such as Co, Ni, and Cu, by vacuum pyrolysis/carbothermal (VPC) treatment of lamellar inorganic-surfactant precursors.

【期刊论文】Colloidal Carbon Spheres and Their Core/Shell Structures with Noble-Metal Nanoparticles**
李亚栋, Xiaoming Sun and Yadong Li*
Angew. Chem. Int. Ed. 2004, 43, 597-601,-0001,():

Colloidal micro-and nanospheres have been of continuous research interest, since their intrinsic properties can be finely tuned by changing parameters such as diameter, chemical composition, bulk structure, and crystallinity. Up to now, they have found a broad range of applications in fields such as drug delivery, biodiagnostics, combinatorial synthesis, and photonic band-gap crystals (PBG).[1-3] The success of these applications strongly depends on the availability of colloidal spheres with tightly controlled size and surface properties.[1,2] However, until now, only amorphous silica and some colloidal polymer spheres can be routinely prepared with satisfactorily narrow size distributions.[4] As-prepared colloidal nano-and microspheres usually have relatively inert surfaces, which make surface modification almost unavoidable before use as supports or templates.[3,5]

esis of nanotubes or nanowires. A particularly significant breakthrough in MX2 (M: Mo or W, X: S or Se) nanotube synthesis was made by Tenne and co-workers.2 Various approaches to other nanotubes, such as BN,3 BxCyNz,4 NiCl2,5 vanadium oxide,6 and InS7 have also been reported, which implies that substances possessing layered structures might be able to form nanotubes under favorable conditions. Here we report the synthesis of bismuth metal nanotubes with diameters ~5nm and lengths ranging between 0.5-5ím. A low-temperature hydrothermal ℃reduction methodith bismuth nitrate [Bi(NO3)3] and aqueous hydrazine solution (N2H4âH2O) at 120℃ has been successfully used to synthesize large quantities of nested bismuth nanotubes. The resulting Bi nanotubes were characterized by X-ray powder diffraction, transmission electron microscopy and composition analysis.

【期刊论文】Artificial Lamellar Mesostructures to WS2 Nanotubes
李亚栋, Yadong D. Li, *, †, ‡ Xiaolin L. Li, † Rongrui R. He, § Jing Zhu, § and Zhaoxiang X. Deng†

A direct pyrolysis method from artificial lamellar mesostructures to nanotubes was developed for the synthesis of tungsten disulfide (WS2) nanotubes. In this process, a tungsten sulfide artificial lamellar mesostructure composite with intercalated cetyltrimethylammonium cations (WS-L) was prepared on the basis of the recently developed template self-assembly of anionic tungstates (WS4 2-) and cationic surfactant molecules (CTA+) in solution under appropriate conditions. After heating of this inorganic-surfactant lamellar composite material in an argon atmosphere to 850℃, bulk quantities of uniform WS2 nanotubes with diameters of 5-37.5nm and lengths ranging from 0.2 to 5ím were produced, which revealed a general rolling mechanism of layered sheets for tubule formation. The observations of transmission electron microscopy are in good agreement with the proposed rolling mechanism.
