Abstract:

In this critical review, we summarized recent novel electrocatalysts on oxygen reduction reaction (ORR). ORR acted as a reaction on cathode in fuel cell. How ORR proceed would directly influence the efficiency of the fuel cell, so that developments of catalysts toward ORR with an advanced activity become highly desirable. Among all the catalysts, the state-of-the-art commercial Pt/C cannot meet the practical application, due to various limitations. Non-metallic material and non-precious metallic materials were studied in recent years. These materials were considered to be a potential choice to provide a good conductivity with a cost-effective and abundant resource in nature. Additionally, a good stability as well as an excellent tolerance toward to the small molecules makes them a perfect candidate for ORR. The development of novel composites to achieve an outstanding performance toward ORR will be a promising program, but still of a challenge.

Key words: Oxygen reduction reaction (ORR), Reaction mechanism, Nonmetal, Non-precious metal
