An organic molecule containing cobalt phosphate (denoted CoPO-GIS) which is isostructural with the zeolite gismondine has been synthesized under solvothermal conditions by using [Co(en)3]Cl3 and phosphoric acid as the reactants and ethylene glycol as the solvent. CoPO-GIS ((H3NCH2CH2NH3)0.5*CoPO4) crystallizes in the monoclinic space group C2/c with a=14.744(3) Å, b=8.850(3) Å, c=10.062(3) Å,β=131.609(19)°, and Z=8. The structure consists of a 3-D network of strictly alternating CoO4 and PO4 tetrahedra interconnected by oxygen bridges, and the charge-balancing diprotonated ethylenediamine cations are highly ordered in the cages of the CoPO4 framework. CoPO-GIS is the only amine-containing cobalt phosphate with a known zeolite topology.

【期刊论文】Miod-bondedconen-framework aluminophosphates and related layered materialas

The structural features, the synthesis and the role of templates in the synthesis for mixed-bonded open-framework aluminophosphates and related layered materials will be reviewed in this article. These aluminophosphate materials difer from the (4,2)-coanected aluminophosphates and zeolites in that they contain TO5 and/or TO6 primary building units or terminal T-O bonds (T stands for AI or P). The extra ligands for the TO5 and TO6 units in the aluminophosphates with framework AI/P = I are either bridging OH groups or H20 molecules in most cases whereas the terminal T--O bonds are either P--OH or P---O species with P=O bonds being prevalent in layered aluminophosphates. Most of TO5 or TO6 containing aluminophosphates are prepared using a cyclic amine or a diamine as the structure directing agent (template). and the aluminophosphates with AI/P < 1 or the layered materials tend to form from an alcoholic medium. Both synthetic conditions and templates play a critical role in determining the composition and structural feature of these materials.

A new layered aluminophosphate [C6H21N4][Al3P4O16] has been synthesized solvothermally by using triethylenetetramine (tetam) as the structure-directing agent and ethylene glycol as the solvent. The structure of the compound was solved by singlecrystal X-ray di4raction analysis. [C6H21N4] [Al3P4O16] crystallizes in the monoclinic space group P21/c with a59.550 (1), b524.064 (1), c59.601(1)As, b597.99 (1)3, V52184.9 (1) As 3 and Z54 (R50.057 and Rw50.052), and its structure consists of [Al3P4O16]3- macroanionic sheets stacked in an AAAA sequence. As primary building units in the individual sheet, alternating PO4 with terminal P5O and AlO4 tetrahedra are corner-shared to form elliptical eight-membered rings as well as four- and six-membered rings. The macroanionic sheets are held together through H bonds between the terminal P5O groups in the inorganic layers and the N atoms of the tetam molecules, which are triply-protonated.

【期刊论文】Mono-sized single-wall carbon nanotubes formed in channels of AlPO4-5 single crystal

An alternative approach to the synthesis of mono-sized and parallel-aligned single-wall carbon nanotubes (WCNs) is reported. The SWCNs are formed in 0.73nm sized channels of microporous aluminophosphate crystallites by pyrolysis of tripropylamine molecules in the channels. They are characterized through transmission electron microscopy, polarized Raman scattering, and electrical transport measurements. Our results would open a door to further detailed studies on the intrinsic properties of carbon nanotubes now in progress.

【期刊论文】Infrared Study on the Dehydroxylation of C60-Loaded MCM-41

e hydrogen-bonded species are eliminated at elevated temperatures under vacuum whereas the isolated ones remain. Loading C60 in the MCM-41 materials greatly changes their dehydroxylation behavior. When the MCM-41:C60 weight ratio is 10:1, at about 400℃ under vacuum, the isolated silanols are reduced to a certain degree whereas the hydrogen-bonded hydroxyls become more resistant to thermal treatment by comparison with those in the parent C60-free samples. Increasing the loading amount of C60 to a MCM-41:C60 weight ratio of 10:3 results in complete removal of both isolated and hydrogen-bonded silanols, at about 350℃. However, the two MCM-41 samples exhibit different infrared spectra at lower evacuation temperatures in the presence of C60, indicative of a discrepancy in the dehydroxylation process between them. It is postulated that during the dehydroxylation, C60 captures hydroxyls from the silanol groups of MCM-41 to form C-H and C-OH species, followed by condensation of the C-OH groups and/or combination of C-OH with C-H.

A family of lamellar aluminophosphates designated APO-Ln (L stands for lamellar and n ) 6, 8, 10, 12, the number of carbon atoms for the occluded template molecules) was synthesized from a mixture of phosphoric acid, aluminum triisopropoxide, ethylene glycol and an unbranched primary alcohol in the presence of an amine as the structure-directing template. The compounds were characterized by X-ray powder diffraction, scanning electron microscopy, MAS NMR spectroscopy, differential thermal, and thermogravimetric analyses. The inorganic layers of APO-Ln are composed of PO4, AlO4, and AlO6 structural units, and the ratio of the octahedral Al to the tetrahedral Al in the as-synthesized compounds is about 1:1. APO-Ln exhibit a distinct weight loss when treated at elevated temperatures, and upon dehydration they adsorb a considerable amount of water. Dehydration-rehydration for APOLn materials is reversible with the dehydrated samples containing almost only tetrahedrally coordinated aluminum.

【期刊论文】Distinguishing the Silanol Groups in the Mesoporous Molecular Sieve MCM-41**

The successful synthesis of M41S materials,[1,2] a new family of novel silicates with uniform mesopores, opened a vast range of applications[3-7] in catalysis, sorption, molecular recognition, electronics, and photochemistry. One of the members of this family of materials is MCM-41, which contains a hexagonal array of mesopores with a pore diameter of 20 100,A depending on the conditions of its synthesis. It is postulated[2] that the inorganic walls around the mesopores of MCM-41 are constructed of disordered SiO4 tetrahedral units, as is also the case for amorphous silicates. NMR studies[2,8] reveal that MCM-41 contains many silanol groups both before and after the template molecules have been removed. These silanols may act as functional groups in chemical reactions or can be utilized to attach molecules having other functional groups. Although the structure and stability of the pores are well understood, little is known about the nature of the silanol groups in MCM-41. To shed some light on this, we monitored the IR absorptions of the silanol groups in template-free MCM-41 as a function of evacuation temperature before and after silylation by chlorotrimethylsilane (CTMS) and chlorotriphenylsilane (CTPS).
