he Nanochemistry Research Team of Beijing University of Chemical Technology (namely Prof. Sun Xiaoming's research group) was established in 2008. The team is affiliated with the State Key Laboratory of Effective Utilization of Chemical Resources. The team is led by the winner of the National Outstanding Youth Science Foundation. There are 5 professors, 4 associate professors, and about 60 doctoral and master students. After years of development, from theoretical research to engineering applications, this research group has formed a research team with complementary advantages and relatively complete functions, and has become a base for the synthesis, separation, assembly, and performance research of nanostructures.

This group of researchers takes the acquisition of structure-controllable monodisperse nanocatalysts and their ordered assemblies as targets, and uses functional and application-oriented, chemical synthesis and density gradient centrifugation as a means to adopt a combination of synthesis and separation and separation. The "direct synthesis" approach was developed to develop liquid phase synthesis methodology and separation analysis methods for monodisperse nanocatalysts and to improve the catalytic performance of inorganic nanoparticle assembly.

The group focused on innovative research on the "energy storage electrode" and "catalytic electrode" in electrochemistry and achieved a series of original achievements and technological breakthroughs. It mainly includes: (1) Development of controllable synthetic methods for inorganic nanostructures, preparation of a series of nano-array electrodes with structurally ordered, highly oriented, uniform size, and fully exposed surface area, achieving significant improvements in the utilization of active materials and cycle stability , Breakthrough the problems of low active material utilization rate, insufficient rate performance and stability in the electrode prepared by traditional coating sintering method; (2) Based on the application requirements of gas evolution reaction electrode, propose the concept of ultra-gassing based on nano-array, through Reduce contact between air bubbles and solid electrodes, reduce bubble overflow size, reduce overpotential, and increase the efficiency of electrolysis and fuel cells; (3) Implement the infiltration control method based on nanoarrays to meet the demand for gas consumption in fuel cells and achieve “ "Super-pro-giveness" improves the efficiency and stability of key reactions in fuel cells. In the industry, the two patents, Silver Nanowire Synthesis and Density Gradient Centrifugal Separation, were transformed to provide a green process and high-quality materials for the preparation of flexible transparent conductive devices.

As of January 2018, the research group published 202 papers and cited more than 24,000 times. Among them, 125 articles have been published in Nat. Commun., Angew. Chem., JACS, Adv. Mater. and other mainstream journals on international materials and chemistry. The total quotation is more than 10,900. He cited >9000. It applied for 40 national invention patents and was authorized 22; 8 international patent applications. In the field of inorganic chemistry and materials, a certain degree of influence was formed. The team leader, Professor Xiaoming Xiao, was named as a high reference scholar in the field of materials science by Esswer Publishing in 2014-2017, and the Royal Society of Chemicals in 2015-2017. Will be selected as top 1% Chinese high cited scholars.

The research team has sufficient funds and complete equipment. It has one of the world's most advanced ultra high-speed centrifuges (100,000 rpm), one gas chromatograph, one CO2 reduction device, one ultraviolet spectrophotometer, and one electrochemical workstation. One Taiwan, high-speed centrifuge, one set of catalyst performance evaluation system, tube furnace, muffle furnace and 14 different function ovens (including vacuum oven, temperature-programmed blast oven, etc.) can successfully complete new materials The synthesis, characterization and catalytic performance evaluation and other experiments.

The task force has extensive domestic and international cooperation. At the domestic level, it has conducted extensive scientific research cooperation with Tsinghua University, Wuhan University, and China University of Science and Technology to jointly promote the development of related fields; and the electrochemical process and technology of materials in Beijing. Laboratory and Beijing Key Laboratory of Environmental Hazardous Chemical Analysis have maintained close cooperation and exchanges. At the international level, it has established long-term partnerships with Stanford University and Yale University in the United States, sending students and teachers to exchange visits every year.

Today, the nanochemical research team of Beijing University of Chemical Technology (professor Sun Xiaoming's research group) has entered the fast-growing fast track. The research group invites interested young people to join in. Whether it is studying master's degree or doing post-doctoral research work, here will provide you with a broader space for development. We agree to welcome all domestic and international research groups/labs/companies to conduct comprehensive exchanges and cooperation with us!
