摘要

光催化CO2还原（Pc-CO2RR）提供了一种将CO2转化为有用化学物质的方法。MOF-on-MOF材料可用于具有本能性能的Pc-CO2RR。这项工作提供了一系列MOF-on-MOF光催化剂，IEF-11@Zr-TCPP通过气固模式用于Pc-CO2RR。在不使用辅助光敏剂和牺牲剂的情况下，IEF-11@Zr-TCPP的CO析出率分别为201.71 μmol g−1 h−1（稀释CO2）和245.34 μmol g−1（纯CO2）。该研究有助于发现新的基于MOF的光催化系统，该系统可以收集太阳能，并且在没有助催化剂的情况下具有高催化活性。

A MOF-on-MOF composite enhances visible light photocatalytic CO2 reduction performance

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 μmol 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.
