Simple fabrication of Z-scheme MgIn₂S₄/Bi₂WO₆ hierarchical heterostructures for enhancing photocatalytic reduction of Cr(<scp>vi</scp>)

Abstract

Direct Z-scheme MgIn 2 S 4 /Bi 2 WO 6 hierarchical heterostructures were simply fabricated, exhibiting distinctly enhanced photocatalytic activity for Cr( vi ) reduction under simulated sunlight irradiation.
