Cover Feature: Importance of Electron Mediator Transparency: Photocatalytic Hydrogen Production from Polyoxometalate using Dye‐double‐layered Photocatalysts (ChemCatChem 4/2023)

The Cover Feature shows the photocatalytic hydrogen production by dual Ru(II)-dye sensitized layered niobate oxide with intercalated Pt cocatalyst in presence of redox-reversible M-substituted polyoxometalate anions (M-POM, M = VIV, MnII). In their Research Article, A. Kobayashi and co-workers found that activity is remarkably higher MnII-POM aq. than VIV-POM despite comparable redox potentials. Their experimental results suggest visible-light transparency surface-immobilized M-POM key factor for H2 activity. More information can be Article co-workers.
