Photocatalysis is a type of catalysis that results in the modification of the rate of a photoreaction - a chemical reaction that involves the absorption of light by one or more reacting species - by adding substances (catalysts) that participate in the chemical reaction without being consumed.

    The direct formation of C–N bonds onto arenes provides a simple route to synthesize a variety of important products. Now, formation of a highly polarized, aminium radical cation enables direct C–H amination, allowing the coupling of an exceptionally broad range of alkyl amines and arenes.

    Covalent organic frameworks (COFs), whose heterogeneous backbones can be easily tuned at the molecular level, are promising photocatalysts for artificial photosynthesis. Sulfone-rich crystalline, wettable COFs have now been shown to exhibit high photocatalytic hydrogen evolution rates with platinum nanoparticles as co-catalysts.

    Photocatalytic water splitting is a route to clean H2, but approaches based on hybrid semiconductor–metal nanoparticles often rely on sacrificial reagents to complete the oxidation half of the overall reaction. New research uses CdS nanocrystals modified with metallic and molecular co-catalysts to simultaneously produce H2 and O2 from water using visible light.
