Here we demonstrate that the utilization of 2,4,6-tris(4-pyridyl)pyridine (tpy) for metal–organic framework modification can greatly improve the photocatalytic performance for CO₂ reduction. The electron-donating nature of tpy enables the charge transfer effect, which induces strong CO₂ binding affinity, facilitates *COOH formation and promotes CO₂-to-CO conversion.

通过配体修饰提高了金属有机骨架对CO2转化的光催化性能。

在这里，我们证明了利用2,4,6-三（4-吡啶基）吡啶（tpy）进行金属-有机骨架改性可以大大提高CO ₂还原的光催化性能。tpy的供电子性质可实现电荷转移效应，从而诱导强大的CO ₂结合亲和力，促进* COOH的形成并促进CO ₂到CO的转化。
