Benzotrithiophene-Based Covalent Organic Frameworks with Rhenium Modified for Artificial Photosynthetic CO Reduction.

Although covalent organic framework (COF)-based photocatalysts for CO reduction reaction has been widely reported, there are still some problems such as poor visible-light absorption and low activity to realize the overall reaction of CO reduction by the artificial photosynthesis strategy. Herein, anchoring the Re carbonyl complex Re(CO)Cl in a benzotrithiophene-based COF has been synthesized for artificial photosynthetic CO reduction. The photocatalytic results demonstrate that BTT-bpy-COF-Re exhibits the highest CORR activity, achieving a rate of 110.

Dual Metallosalen-Based Covalent Organic Frameworks for Artificial Photosynthetic Diluted CO Reduction.

Directly converting CO in flue gas using artificial photosynthetic technology represents a promising green approach for CO resource utilization. However, it remains a great challenge to achieve efficient reduction of CO from flue gas due to the decreased activity of photocatalysts in diluted CO atmosphere. Herein, we designed and synthesized a series of dual metallosalen-based covalent organic frameworks (MM-Salen-COFs, M: Zn, Ni, Cu) for artificial photosynthetic diluted CO reduction and confirmed their advantage in comparison to that of single metal M-Salen-COFs.
