Defective phase engineering of S-Scheme TiO2-SnS/SnS2 core-shell Photocatalytic nanofibers for elevated Visible light responsive H2 generation and Nitrogen fixation

To promote the fast separation of photogenerated charge carriers and promote stability, we designed core–shell TiO 2 –SnS/SnS 2 heterostructures with enriched oxygen-related defect states without compromising their morphology.
