It's all about the levels: Hydrazine treatment of a Pt/C catalyst successfully yielded nitrogen-doped Pt/C (Pt/NC) with controlled nitrogen content. The as-prepared Pt/NC catalysts exhibited enhanced electrocatalytic activity and stability toward the oxygen reduction reaction (ORR), and the corresponding ORR activity is highly dependent on the level of nitrogen-doping (see figure; RHE=reversible hydrogen electrode).
