Abstract

Dual-functional photocatalysis for H₂ evolution with the simultaneous mineralization of 4-chlorophenol was achieved under de-aerated conditions using a Cr₂O₃/Rh/SrTiO₃ photocatalyst which has Rh nanoparticles covered with a thin Cr₂O₃ barrier layer to selectively control and maximize the dual-functional photocatalytic activity.
