英文摘要	crystal facet dependence, as the crucial factor for semiconductor photocatalysis, is a significant strategy for optimizing the reactivity of photocatalyst. given that there is a strong correlation between crystal facet and photocatalytic activity, we herein designed the ag@agcl core shell structure decorated on (040) crystal facet of bivo4 (ag@agcl/bivo4) as a hierarchical z-scheme photocatalytic system by a simple route. in this hybridization system, the metallic ag species not only act as the solid-state electron mediator, but can also absorb the photons from incident light and present the spr-effect. as expected, such ag@agcl/bivo4 heterostructure exhibits highly efficient photocatalytic performance and the first-order kinetic constant of photodegradation of rhodamine b (rhb) is 300 times of pristine bivo4. moreover, by means of the eis, lsv and l-t measurements, the ag@agcl/bivo4 heterostructure also presents extraordinary photoelectrochemical performance. focus is then given toward a novel perspective for understanding the mechanism of interfacial charge transfer of photocatalytic on the basis of the bivo4-based all-solid-state z-scheme photocatalyst. this work is expected to open up new insights into the architectural design of novel z-scheme photocatalysts with high photoactivity and further utilization in the field of environmental or energy.
