Diatomite-Templated Fabrication of Porous N, S-Co-Doped Carbon as High-Performance Catalyst for Oxygen Reduction
Oxygen reduction reaction (ORR) catalysts free of noble metals serve an essential function in boosting the practical deployment of fuel cells and metal–air batteries. Herein, an N, S-co-doped porous carbon electrocatalyst was fabricated using polyacrylonitrile (PAN), thiourea and diatomite as the precursors, sulfur sou...
