A Zr‐based metal‐organic framework has been synthesized and employed as a catalyst for photochemical carbon dioxide reduction coupled with water oxidation. The catalyst shows significant carbon dioxide reduction property with concomitant water oxidation. The catalyst has broad visible light as well as UV light absorption property, which is further confirmed from electronic absorption spectroscopy. Formic acid was the only reduced product from carbon dioxide with a turn‐over frequency (TOF) of 0.69 h⁻¹ in addition to oxygen, which was produced with a TOF of 0.54 h⁻¹. No external photosensitizer is used and the ligand itself acts as the light harvester. The efficient and selective photochemical carbon dioxide reduction to formic acid with concomitant water oxidation using Zr‐based MOF as catalyst is thus demonstrated here.

蒽基金属有机骨架，可选择性地将二氧化碳二氧化碳光还原为甲酸并与水氧化

已经合成了基于Zr的金属有机骨架，并用作光化学二氧化碳还原和水氧化的催化剂。该催化剂显示出显着的二氧化碳还原性能，同时伴随着水的氧化。该催化剂具有宽的可见光以及紫外线吸收特性，这由电子吸收光谱进一步证实。甲酸是二氧化碳中除氧以外的唯一还原产物，其周转频率（TOF）为0.69 h ^-1，而氧的TOF为0.54 h ^-1。没有使用外部光敏剂，并且配体本身充当了光收集器。因此，本文证明了使用基于Zr的MOF作为催化剂的同时将水氧化有效，选择性地将光化学二氧化碳还原为甲酸。
