Co(OH)2 water oxidation cocatalyst-decorated CdS nanowires for enhanced photocatalytic CO2 reduction performance

A Co(OH)₂nanoparticle decorated CdS nanowire (Co(OH)₂/CdS) based heterostructured photocatalyst was prepared. The optimal Co(OH)₂/CdS photocatalyst achieves a CO production rate of 8.11 μmol g⁻¹h⁻¹under visible light irradiation (λ> 420 nm).
