摘要:
Highly active and stable catalysts towards electrochemical oxygen evolution reaction are crucial for the efficient water splitting and sustainable hydrogen generation. Here we report a novel mesoporous Co3O4 with the surface decoration of mixed CoOxPy species towards efficient OER catalysis. The material is synthesized from a simple carbon template derived from p-phenylenediamine bisulfate followed by low temperature phosphorization. Unlike traditional methods, silica intermediates are not involved during synthesis, improving the overall safety...
