Synergy of charge pre-separation and direct Z-scheme bridge in BiVO4{0 4 0}/Ag6Si2O7 photocatalyst boosting organic pollutant degradation

A direct Z-scheme photocatalyst with superior photocatalytic activity was achieved by selectively depositing Ag6Si2O7 nanoparticles on the {0 4 0} facets of BiVO4. This photocatalyst demonstrates boosted charge separation efficiency and strong redox capability owing to the synergistic effect of the charge pre-separation effect on the faceted BiVO4 and the optimal charge transfer pathway in the direct Z-scheme photosystem.
