Shanghai silicates have been applied in the research of electrocatalysis of heterogeneous atom doped graphene
In recent years, research groups led by Liu Xi and Wang Jiacheng, researchers of the Shanghai Institute of Ceramics, Chinese Academy of Sciences, have developed various synthesis routes for heteroatom-doped graphene electrocatalytic materials, including nitrogen doping, sulfur doping, and A series of innovative research results in the application of binary doping (N,B;N,S;N,P) graphene electrocatalysis was published in Nano Research, 2016, 9(3), 808–819;Carbon , 2016, 102, 58-65; Scientific Reports, 2015, 5, 9304, etc. Recently, Tsinghua University Press published the research article “Novel Synthesis of N-doped Graphene as an Efficient Electrocatalyst towards Oxygen Reduction†(Nano Research, 2016, 9(3), 808–819) published by Nano Research as a research item. Highlights are recommended on the "EurekAlert! Chinese" page hosted by the American Association for the Advancement of Science (AAAS). The first author of this paper is Ma Zhaoguang, a young researcher of the research group, and Liu Jianjun, a researcher of the Shanghai Silicate Center Computation Center, who provided theoretical calculations for the evolution of nitrogen-doped species in graphene. The research work combined experimental and theoretical simulations and found that the increase of pyridine nitrogen can significantly improve the performance of electrocatalytic oxygen reduction, providing experiments for the controversial "effect of nitrogen-doped species on the electrocatalytic activity sites of carbon-based materials." Rationale and scientific explanation. This result is also similar to the results of a recent study by a Japanese research group published on Science (Guo et al, Active Sites of Nitrogen-doped Carbon Materials for Oxygen Reduction Reaction Clarified using Model Catalysts, Science, 2016, 351(6271), 361 -365). The Japanese team believes that pyridine nitrogen changes the Levis alkalinity of the adjacent carbon atoms, thereby improving the oxygen reduction performance.
