Visible Light-Driven Metal-Organic Framework-Mediated Activation and Utilization of CO for the Thiocarboxylation of Olefins.

Visible light-mediated photoredox catalysis has emerged to be a fascinating approach for the activation of CO and its subsequent fixation into valuable chemicals utilizing renewable and inexhaustible solar energy. Although great progress has been made in CO photoreduction, visible light-assisted organic synthesis using CO as a reactive substrate is rarely explored. Herein, we report an efficient, facile, and economically viable photoredox-mediated approach for the synthesis of important β-thioacids via carboxylation of olefins with CO and thiols over a porous functionalized metal-organic framework (MOF), Fe-MIL-101-NH, as a photocatalyst under ambient conditions.

Metal-Free Triazine-Based 2D Covalent Organic Framework for Efficient H Evolution by Electrochemical Water Splitting.

Hydrogen evolution reaction (HER) by electrochemical water splitting is one of the most active areas of energy research, yet the benchmark electrocatalysts used for this reaction are based on expensive noble metals. This is a major bottleneck for their large-scale operation. Thus, development of efficient metal-free electrocatalysts is of paramount importance for sustainable and economical production of the renewable fuel hydrogen by water splitting.
