Electrocatalytic Oxygen Reduction Reaction on 48-Tungsto-8-Phosphate Wheel Anchored on Carbon Nanomaterials
Regardless of great efforts, the development of novel low cost electrocatalysts with high electrocatalytic activity for the oxygen reduction reaction (ORR) remains a real challenge. This is a setback for the mass commercialization of one of the eco-friendliest alternative power sources: fuel cells (...
