Recent progress in SnO2/g-C3N4 heterojunction photocatalysts: Synthesis, modification, and application

Semiconductor photocatalysts, especially semiconductor heterojunctions, have great development potential in the field of photocatalysis. SnO2/g-C3N4 heterojunction has shown excellent photocatalytic performance rather than single SnO2 or g-C3N4, particularly for visible-light-driven photocatalysis. In this review, the synthesis methods of SnO2/g-C3N4 heterojunction are summarized. Then, the modification strategies of morphology control, defect introduction and multiple structural optimization strategies are highlighted. Morever, the possible mechanisms and applications in environment remediation and energy conversion of SnO2/g-C3N4 heterojunction are discussed. Finally, the challenges and perspectives of SnO2/g-C(3)N4 heterojunction are also proposed. (c) 2022 Elsevier B.V. All rights reserved.
