Abstract
Fuel cells are an important and promising energy system which has attracted lots of attention. The research on non precious metal catalysts is extremely important for the development of fuel cells. In this work, we fabricated metal organic hybrids (MOH) from chitosan, phytic acid, and CoCl2 through a simple chemical method, and further obtained the Co, N, and P co-doped 3D porous carbon material, with the Co atoms exhibiting good monodispersity on the surface. Due to the size effect brought by the single atom doping of Co and the influence of N and P doping on the microenvironment of the active center, the obtained Co-NPC-6 M exhibits excellent catalytic performance for ORR in the alkaline aqueous electrolyte solution.
