Abstract |
Development of high-performance catalysts is very crucial for the commercialization of sustainable energy conversion technologies. Searching for stable, highly active, and earth-abundant multifunctional catalysts has become a critical issue. In this study, we report the synthesis of cobalt vanadate (Co3V2O8) nanosheets and their highly efficient bifunctional electrocatalytic activities toward oxygen evolution (OER) and reduction (ORR) reactions. We observed that Ni-doped Co3V2O8 exhibits excellent catalytic activity and stability for OER and ORR, which is better than Co3V2O8. On the basis of the promising bifunctional activity of the as-obtained catalyst, this electrocatalyst was further integrated into a rechargeable Zn-air battery. This work might provide a strategy to design robust and earth-abundant electrocatalysts for water splitting, and inspire the development of next-generation electrocatalysts for renewable energy applications. |
