Silver-molybdate electrocatalysts for oxygen reduction reaction in alkaline media

A novel non-Pt catalyst silver-molybdate electrocatalyst prepared by hydrothermal method was used for the oxygen reduction reaction (ORR) in alkaline solution for the first time. These silver-molybdate electrocatalysts showed catalytic activity for ORR and higher durability than Pt/C catalyst. Such catalyst with advantages including facile synthesis, low cost and good durability could be a valuable catalyst for oxygen reduction reaction and be a potential candidate for application in alkaline fuel cells and metal–air batteries.
