| Outline of Annual Research Achievements |
We prepared bimetal metal-organic frameworks (BiMOF)-derived porous carbon through a self template-directed synthesis strategy followed by high temperature pyrolysis. The dimensions, morphologies, and compositions of BiMOFs were controlled by adjusting reaction conditions (e.g., time, temperature, solvent). Single-atom doped porous carbon could be obtained through one-step programmed carbonization, as well. Preliminary electrochemical performances of sulfur cathode was carried out through cyclic voltammetry (CV), galvanostatic charge/discharge, and EIS. The effects of morphology, porosity, and single-atom doping of carbon-based materials on the performance of sulfur cathodes were systematically investigated. Some of results were published already in international journals.

| Strategy for Future Research Activity |
The rational design and fabrication of ordered mesoporous materials with highly exposed surface area are of great significance to address the fundamental challenges in electrochemistry-related applications by providing more active sites and fast ion/gas diffusion channel.
In FY 2020, a self-template method will be reported to prepare hollow-structured and ordered mesoporous carbon (HOMC) nanoplates by depositing resol-F127 micelles onto the surface of metal-organic-framework (MOF) nanosheets, followed by hydrothermal reaction and carbonization. The parameters influencing the morphology and microstructure of the HOMC materials, i.e., the MOF-to-resol-F127 ratio and the concentration of resol-F127 micelles, will be systematically investigated.
