Controllable growth of SnS2/SnO2 heterostructured nanoplates via a hydrothermal-assisted self-hydrolysis process and their visible-light-driven photocatalytic reduction of Cr(vi)

Abstract

A novel and facile hydrothermal-assisted self-hydrolysis route has been proposed for the controllable preparation of SnS₂/SnO₂ heterostructured nanoplates (HNPs). Benefiting from the unique structural features, the as-prepared SnS₂/SnO₂ HNPs exhibit significantly enhanced visible-light-driven photocatalytic activity in the reduction of aqueous Cr(VI).
