Facile fabrication of B-rGO/ZnFe ₂ O ₄ p–n heterojunction-based S-scheme exciton engineering for photocatalytic Cr( <scp>vi</scp> ) reduction: kinetics, influencing parameters and detailed mechanism

Abstract

(ZnF) and B-rGO, respectively. The intimate interfacial contact, excellent photon-harvesting properties, effective exciton segregation and availability of active electrons are some factors responsible for enhanced photocatalytic Cr(vi) reduction. In order to fulfill the demand of applied waste-water management, the influences of various photocatalyst amounts, pH values and co-exiting ions on photocatalytic activities were evaluated. Finally, this work provides a way to fabricate S-scheme-based p-n-heterostructures for photocatalytic wastewater treatment.
