Photocatalysts can use visible light to convert CO into useful products. However, to date photocatalysts for CO conversion are limited by insufficient long-term stability and low CO conversion rates. Here we report hybrid photocatalysts consisting of conjugated polymers and a ruthenium(ii)-ruthenium(ii) supramolecular photocatalyst which overcome these challenges.

Article Synopsis
- - Rhenium(i) complexes, particularly c-[Re(diimine)(CO)(L)], are commonly researched as photocatalysts for CO reduction, but their selective reduction mechanisms are not fully understood despite various studies.
- - A new supramolecular photocatalyst, RuC2Re, shows exceptional efficiency and selectivity in producing CO during photocatalytic reactions, with key intermediates identified through time-resolved infrared spectroscopy and steady-state irradiation.
- - The study clarifies the mechanistic steps in the CO reduction process involving RuC2Re and its intermediate RuC2Re(COOH), including kinetics of recovery processes and the formation of side reaction products that may also participate in CO formation.

The oxyfluoride PbFeOF was investigated as a photoanode material and as an electrocatalyst for water oxidation. PbFeOF powder, which was synthesized by a high-pressure method and had an estimated bandgap of 2.1 eV, was deposited onto a fluorine-doped tin oxide (FTO) substrate.

Promotional effects of co-existing ions on overall water splitting into H and O have been studied in bulk-type semiconductor photocatalysts (, TiO), but such an effect remains unexplored in two-dimensional nanosheet photocatalysts. Here we examined the effect of co-existing ions on the photocatalytic water splitting activity of Pt nanocluster-intercalated KCaNbO nanosheets. Interestingly, not only anions, as usually observed in bulk-type photocatalysts, but also cations had a significant influence on the photocatalytic performance.
