摘要：
It is desirable to improve the methanol oxidation abilityof heterojunctioncatalysts because of their potential in the field of electrocatalysis.In this article, we have integrated CuO/Co3O4 heterojunction with porphyrin (TCPP) for TCPP/Cu2Co1. The results demonstrate that the specific surface area andelectrochemical active surface area (ECSA) are enhanced, and the unblockedseparation and transfer of photogenerated charges are guaranteed bythe matched band energy of CuO, Co3O4, and TCPP.As such, the photocatalytic methanol oxidation reaction (MOR) performanceand stability of TCPP/Cu2Co1 are significantlyenhanced compared with those of Cu2Co1. Thisstudy provides a promising pathway for the design of MOR catalystswith high MOR activity.
