Construction of dual-channel for optimizing Z-scheme photocatalytic system
چکیده انگلیسی


- Visible-light Z-scheme system was selectively built on the {010} facet of BiVO4.
- Construction of dual-channel realized effective separation of charge carriers.
- The system realized complementarity of interfacial engineering and facet engineering.
- The underlying photocatalysis mechanism for organic dye degradation was proposed.

A ternary all-solid-state visible-light Z-scheme photocatalytic system BiVO4/Au@CdS is prepared by means of a two-step route, which is selectively built on the {010} facet of BiVO4 crystals in this system. Vectorial migration of photogenerated charge carriers through two order transmission channels in Z-scheme photocatalytic system further prolongs the mean free path of electrons, realizing effective separation of photogenerated charge carriers and possesses high redox ability. As expected, such BiVO4/Au@CdS Z-scheme photocatalytic system exhibits highly efficient photocatalytic performance. Our current work is expected to offer new insight into construction of dual separation channels for rational design and compound of photocatalyst with high performance.
