By synthesizing a MnV2O6 interface-modified V2O5/g-C3N4 direct solid Z-scheme heterostructure, the photocatalytic activity of the Z-scheme heterostructure has been significantly enhanced. This work provides new insights for fabricating high-performance Z-scheme heterostructure photocatalysts with low cost and high activity.
Developing highly active and low cost photocatalyst is of great importance for solar energy conversion and pollutant degradation. In this work, we reported a simple synthesis of MnV2O6 interface modified V2O5/g-C3N4 direct solid Z-scheme heterostructure for the first time. Without the addition of any noble elements, the MnV2O6 modified V2O5/g-C3N4 Z-scheme heterostructure exhibit significantly enhanced photocatalytic activity under visible irradiation (lambda > 420 nm). The superior visible photocatalytic activity is owing to the introduction of MnV2O6 at the interface, which would further promote the separation of charge carriers in Z-scheme pathway and extend the visible response for the V2O5/g-C3N4 heterostructure. This work may provide new physical insight for fabricating high-performance Z-scheme heterostructure photocatalysts with low cost and highly active performance. (C) 2021 Elsevier B.V.
