The three different morphologies BiPO nanocrystals(rods, spindles and spindle-like assembled nanosheets) were successfully synthesized by hydrothermal method. The as-prepared products were characterized using X-ray diffraction analysis, infrared analysis, scanning electron microscopy analysis and ultraviolet-visible diffuse reflectance analysis. XRD results show that BiPO samples presented monoclinic phase monazite structure, hexagonal phase + monoclinic phase and hexagonal phase + monoclinic phase monazite structure. The results showed that the BiPO has superior photocatalytic activity with the addition of SDS,and IPA, SO and BQ have been used to capture ·OH, h+ and ·O, respectively. Capture of ·OH and h+ in BiPO crystals clearly showed that ·OH and h+ played a major role in the photocatalytic proc

Synthesis and characterization of porous boehmite AlOOH nanospindle via hydrothermal route and its application in Pb（Ⅱ） removal

中国化学会第十届全国无机化学学术会议

作者：吴秀娟丁欣然王艺慧刘点点王洁 dongen zhang Department of Chemical Engineering Huaihai Institute of Technology Jiangsu Key Laboratory of Function Control Technology for Advanced Materials School of Chemistry and Chemical Engineering Nanjing University

In this paper, Ni(NO)·6HO was used as the nickel source, Fe(NO)3·9 HO as the iron source, thiourea as the sulfur source by hydrothermal method(the amount of thiourea was changed respectively to be 0.1 g, 0.15 g, 0.2 g, 0.25 g) to compound Fe-Ni alloy materials, and the composite products were loaded onto carbon cloth. It was found that when the amount of thiourea was 0.15 g, the composite has the best hydrogen evolution performance.

The controllable synthesis of boehmite AlOOH porous nanostructures is of great importance due to their wide potential applications in adsorbents, catalyst supports and so on. Herein we firstly fabricate boehmite AlOOH porous nanospindles through the hydrothermal reaction between Al（NO3）3·9 H2O and DMF with surfactant PVP. By parallel experiments, we found that the added amount of Al（NO3）3·9 H2O, reaction temperature and surfactant affect the products final morphology. Due to their porous nature, The Pb（II） adsorption behaviors of AlOOH products were evaluated. Results show that the best pH for adsorption is 5.0 and the adsorption equilibrium time is 120 min. The adsorption is an endothermic process and the saturated adsorption amount is 53.04 mg/g at 25 °C, suggesting their potential environmental application in Pb（II） removal from aqueous solutions.

Microfluidic devices, as a new miniaturized platform stemming from the field of micro-electromechanical sys-tems, have been used in many disciplines. In the field of chemical reactions, microfluidic device-based microreac-tors have shown great promise in building new chemical technologies and processes with increased speed and reli- ability and reduced sample consumption and cost. This technology has also become a new and effective tool for precise, high-throughput, and automatic analysis of chemical synthesis processes. Compared with conventional chemical laboratory batch methodologies, microfluidic reactors have a number of features, such as high mixing ef- ficiency, short reaction time, high heat-transfer coefficient, small reactant volume, controllable residence time, and high surface-to-volume ratio, among others. Combined with recent advances in microfluidic devices for chemical reactions, this review aims to give an overview of the features and applications of microfluidic devices in the field of chemical synthesis. It also aims to stimulate the development of microfluidic device applications in the field of chemical reactions.

为提高图像匹配的精度和速度,利用离散余弦变换(DCT)和自适应人类学习优化算法(ASHLO),提出了一种快速并且抗噪性强的图像匹配算法。该方法利用当前搜索位置子图像和模板图像离散余弦变换后的参数构造适应度函数,经过迭代寻优寻找最优匹配位置。将该算法在正常情况下以及不同噪声情况下与穷举法、基于粒子群算法(PSO),基于人工蜂群算法(ABC)的图像匹配算法进比较。实验结果表明,该算法可以获得较高的准确率,成功匹配率约95%,且速度快,抗噪性强。
