Defective phase engineering of S-scheme TiO₂–SnS/SnS₂ core–shell photocatalytic nanofibers for elevated visible light responsive H₂ generation and nitrogen fixation

Abstract

To promote the fast separation of photogenerated charge carriers and promote stability, we designed the core-shell TiO2-SnS/SnS2 heterostructures with a mixed-phase shell wall of the SnS/SnS2 composition with enriched oxygen-related...
