Abstract
Considering environmental protection and sustainable development, fuel cells have always been an ideal choice for clean energy. For the performance of fuel cells, the anode catalysts are a key consideration. In the work reported, we designed a new type of anode catalyst, in which graphitic carbon nitride was used as the substrate and transition metal iron as the supported atom. The calculation results were characterized by adsorption energy, reaction energy barrier, potential energy surface and charge analysis. Based on density functional theory, the gradual decomposition of methanol molecules on the catalyst is realized; the decomposition products are oxidized to reduce the formation of CO, and the efficiency of anode catalysis is improved, which provides a new idea for the design of anode materials for methanol fuel cells.
