Presided over a National Natural Science Foundation project. So far, he has published 10 academic papers in academic journals and conferences at home and abroad, of which 10 are included in SCI.
1. MOF/graphene composites were prepared for the precursor system using manganese-based MOF materials, and MnO nanoparticles highly dispersed in nitrogen-doped graphene were obtained by pyrolysis (MnO@NC-G). This compound plays an efficient catalytic role in the gas electrode of Li-CO2 battery, which greatly reduces the overpotential of the battery and improves the cycle and rate performance of the battery.
2. MOF was applied to the gas electrode of Li-CO2 battery using its monodisperse metal site as a catalyst to promote the decomposition of the discharge product Li2CO3. The effects of metal type, pore size and other factors on battery performance were systematically studied, and it was found that manganese divalent can be used as the catalytic active center, which can effectively reduce the overpotential of battery charging, and the high specific surface area of MOF is conducive to improving the maximum discharge capacity of the battery.
3. MOF film was prepared on conductive carbon cloth by hot pressing method, and a layer of cobalt nanoparticles highly dispersed in nitrogen-doped porous carbon was obtained by high temperature pyrolysis. As a barrier layer in Li-S battery, the modified carbon cloth not only significantly improves the utilization rate of active substances, but also alleviates the shuttle effect of sulfur, and improves the reversible capacity and rate performance of the battery.
