  • Although surface-bound molecular catalysts offer well-defined active sites on heterogeneous supports, it is challenging to identify key radical intermediates in the reaction mechanism. Now, a characterization method has been developed that combines film electrochemistry and EPR spectroscopy to track radical intermediates in real time, exemplified by alcohol oxidation with a surface-immobilized nitroxide.

  • Visible-light-driven dual photoredox catalysis often uses expensive metals, such as iridium. Now, a photocatalytic approach using a Ni single-atom carbon nitride catalyst is reported for the C–O cross-coupling of carboxylic acids and alkyl halides, demonstrating broad functional group tolerance, short reaction times, facile recovery and excellent stability.

  • In photoelectrochemical (PEC) cells, water oxidation to O2, when coupled to CO2 reduction, typically requires a pair of light absorbers or an applied bias voltage. Now, a bias-free PEC cell with a single sunlight absorber drives simultaneous CO2 reduction to give formate, and the oxidation of an organic substrate in aqueous conditions.
