近期，我系宋宁静副教授与山西大学马灿良副教授合作的论文“A novel method ofenhancing the nitrogen content in biomass hard carbon:pyrolysis-deposition-self-doping strategy”在《International Journal of Energy Research》期刊发表。

论文简介如下：

In order to make the most of the nitrogenelement in the raw material and realize the self-doping of nitrogen element inthe carbon material to the maximum extent, we invent a method calledpyrolysis-deposition-self-doping (PDSD). In this paper, we select the corn cobas raw materials, during the pyrolysis process, the open and closed environmentis selected, respectively. The results show that N content of the materials preparedby pyrolysis-deposition- self-doping in confined environment reach 5.63 at.%,while in the open environment, the N content of material is only 0.93 at.%. Meanwhile,materials prepared in a confined environment have a higher ordered degree. Inorder to further verify the advantages of PDSD method in a closed environment,we further test the performance of the material for sodium ion battery, andfind that the material prepared in a closed environment had better cycling andrate performance. This fully proves the advantages of PDSD method in a closed environment,which may lay a foundation for subsequent material preparation and theoreticalresearch.
