【期刊论文】Self-assembly of ZnO Nanoparticles and the Preparation of Bulk ZnO Porous Nanosolids

Novel bulk ZnO porous nanosolids were prepared by a unique solvothermal hot-press method, using ZnO nanoparticles and several kinds of solvents as the starting materials. It was found from the experiments that ZnO nanoparticles underwent a "self-assembly process" under some specific hydrothermal hot-press conditions. As a result, some "nanoflowers" formed. The results showed that porous nanosolids with uniform pore diameters could be obtained when water distributed uniformly among the ZnO nanoparticles. On the contrary, if the uniformity of the distribution of water was poor, "nanoflowers" would appear in the water-rich region. It was also found that the photoluminescence of ZnO porous nanosolids was affected by the self-assembly phenomenon. In addition, the experimental results also showed that, both the volume and diameters of the pores could be adjusted by changing either the hot-press temperature, pressure or the kinds of solvents.

本文利用AlCl3和Li3N作为前驱物,利用过量Li3N与水反应大量放热现象,引发两种前驱物之间的固相反应合成了AlN纳米粉。X-射线衍射分析、红外吸收光谱以及透射电子显微镜测试结果表明,利用这种新的合成方法制备的氮化铝主要是六方相,而且颗粒细小、粒度分布比较均匀。另外,这种方法反应迅速、操作过程简单,便于降低制备成本和扩大制备规模。

In this paper, the experimental results of synthesizing BN nanocrystals by both solvothermal and hydrothermal routes have been briefly reviewed. At the end of this paper, the results of utilizing BN nanocrystals as the catalyst for the "polymerization" of benzene are also discussed. The full text contains five parts. 1. Introduction to the synthesis of cubic boron nitride. a. Results of synthesizing cBN by high temperature & high pressure route; b. Results of the synthesis of both hexagonal and cubic boron nitride by sovlothermal route. 2. Synthesis of BN nanocrystals by solvothermal route. a. Preparation of hBN nanocrystals by reacting BBr3 with Li3N; b. The reaction of BCl3 with Li3N for the synthesis of hBN and cBN and cBN nanorods; c. The preparation of hBN nanocrystals from BCl3 and NaN3. 3. Application of structural induction effect on controlling the phases in BN nanocrystals. a. Synthesis of cBN nanocrystals at medium temperature by the induction effect of bulk 316L stainless steel plates; b. Synthesis of cBN nanocrystals at 200°C under the structural induction effect of GaP nanocrystals; c. Preliminary comparison of the induction effects of GaP and Ni nanocrystals. 4. Synthesis of cBN nanocrystals by hydrothermal synthesis route. a. Synthesis of oBN and cBN by the reactions of NaN3, H3BO3 and P in aqueous solutions; b.

【期刊论文】Some Key Factors Affecting the Formation of BN Nanocrystals Under Hydrothermal Conditions

Boron nitride (BN) nanocrystals with high crystalline perfectness and high yield have been successfully prepared by hydrothermal synthesis route. The experimental results show that the addition of N2H4•H2O and NH4Cl into the reaction mixture significantly improved the perfectness and yield of cBN and oBN nanocrystals. Furthermore, the results of powder X-ray diffraction (XRD), transmission electron microscopy (TEM), selective area electron diffraction (SAED) and high-resolution transmission electron microscope (HRTEM) analysis proved that the major phases in the samples are orthorhombic boron nitride (oBN) and cubic boron nitride (cBN).

【期刊论文】Phase-Selective Synthesis of Cubic Boron Nitride in Hydrothermal Solutions

A novel "in situ phase-selective route" has been developed, and it was used for the synthesis of cubic boron nitride (cBN) under hydrothermal conditions. The results showed that, if H3BO3, NaN3 and N2H4•H2O were mixed at room temperature and ambient pressure, explosion boron nitride (eBN) was the dominant phase in the sample prepared at 300℃ and 10 MPa. On the contrast, if the reactants were separated with each other at room temperature and ambient pressure, and slowly mixed at high temperature and high pressure (namely, 300℃ and 10MPa) conditions, cBN crystals as large as 0.5mm could be synthesized. This method was called "in situ phase-selective route", it should also be an effective method for the synthesis of diamond crystals in solvothermal and hydrothermal solutions.

【期刊论文】Application of Reaction Coupling Effect in the Synthesis of BN Crystals from Aqueous Solutions

Boron nitride (BN) crystals were synthesized from aqueous solutions by reaction coupling effect. The effects of white phosphor (P), ammonium chloride (NH4C1) and the reaction temperature on the yield and crystalline perfectness of BN crystals have been explored. The results showed that, the existence of P in the reaction mixture significantly increased the yield and perfectness of the BN crystals. BN crystals grew larger and more perfect when the temperature increased from 300℃ to 550℃.The yield and perfectness of BN can also be improved greatly by adding NH4C1 to the reaction mixture. The samples were characterized by powder X-ray diffraction (XRD), Fourier transformation infrared absorption spectrum (FTIR), Transmission electron spectroscopy (TEM) and Selective area electron diffraction (SAED).

【期刊论文】Synthesis of Cubic Boron Nitride at Low Temperature and Low Pressure Conditions

Cubic BN (cBN) nanocrystals were synthesized by reacting BBr3 and Li3N at 480℃ and 10-20MPa. The temperature and pressure were much lower than that of previous processes. The sample was characterized by X-ray powder diffraction (XRD), electron diffraction (ED), Fourier transformation infrared spectroscopy (FTIR) and X-ray photoelectron spectra analysis (XPS) measurements. The results have showed that cBN, hBN and oBN (orthorhombic phase prepared by shock-wave compression, with a=0.86nm, b=0.774nm and c=6.35nm) coexist in the sample. But the cubic BN is the dominant phase, and this conclusion has been confirmed by both XRD and ED. Analysis of XPS spectra has showed that the average composition of the sample is about B1.1N1.0.

On behalf of all the authors, we want to express our thanks to Dr. Sachdev, because he has wrote a comment on the paper "synthesis of cubic boron nitride at low temperature and low pressure conditions". We have learned very much from Dr. Sachdev's comment (referred as "comment" in this article), and find some negligences in our above mentioned paper (referred as "paper" in this article). But Dr. Sachdev also made some obvious mistakes in the "comment", the detailed analysis can be found in the following article.

InP and GaP nanocrystals were prepared by the reaction of yellow phosphorus with indium and gallium metal in benzene. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED) measurements. The self-assembly phenomenon of InP and GaP nanocrystals was observed. Compared to the other methods, our synthesis route is very simple and the products are less contaminated.
