Cover Picture: Hydrogen‐Bond‐Network Breakdown Boosts Selective CO2 Photoreduction by Suppressing H2 Evolution (Angew. Chem. Int. Ed. 21/2024)

Hydrogen bond network breakdown in the CO2 photoreduction system can suppress H2 evolution and boost CO production, as reported by Chengcheng Liu, Weiqiao Deng et al. in a Research Article (e202316991). Photosensitive poly(ionic liquid)s are designed as photocatalysts owing to their robust hydrogen bonding with solvents. The suppression of H2 evolution in photocatalytic CO2 reduction was effectively achieved by disrupting the hydrogen bond network with solvent additives.
