Reduced graphene oxide-modified Z-scheme g-C3N4/CdS photocatalyst with a staggered structure for the enhanced photoreduction of CO2

The prepared Z-scheme CN/CdS@rGO photocatalyst formed a 2D/2D staggered structure: CN/CdS, CdS/rGO and CN/rGO, which provided more paths for electron transport and greatly improved the photocatalytic CO 2 reduction efficiency.
