摘要：

Photocatalytic CO2 reduction (Pc-CO2RR) offers one way to covert CO2 into useful chemicals. MOF-on-MOF materials can be made for Pc-CO2RR with instinct performance. This work provides a family of MOF-on-MOF photocatalysts, IEF-11@Zr-TCPP for Pc-CO2RR via the gas-solid mode. Owing to the appropriate synergistic effect between two MOF components, IEF-11@Zr-TCPP displayed high CO evolution rates of 201.71 (in pure CO2) or 245.34 mu mol g- 1 h-1 (in diluted CO2) respectively, without auxiliary photosensitizers or sacrificial agents. This study helps to discover new MOF based photocatalytic systems that collect solar energy and exhibit high catalytic activity with no cocatalyst.
