Construction of SnNb2O6/MgIn2S4 heterojunction photocatalysts with enhanced visible-light-driven activity for tetracycline hydrochloride degradation and Cr(vi) reduction

A novel type II SnNb 2 O 6 /MgIn 2 S 4 composite photocatalyst was prepared. The prepared composite photocatalyst exhibited significantly improved photocatalytic activity for Cr( vi ) reduction and tetracycline hydrochloride degradation under visible light.
