Figure Abstract

Caption

Photocatalytic water splitting for H2 evolution is expected to be a feasible strategy to alleviate environmental and energy pressure. A defect-engineered TiO2-Ov/Zn0.5Cd0.5S S-scheme heterojunction is designed and constructed by in situ growing Zn0.5Cd0.5S nanoparticles on flower-like TiO2 microspheres with oxygen vacancies. The defect-engineered S-scheme heterojunction with dual charge transfer pathways endows excellent light absorption ability, effective spatial separation and transfer of photo-induced charge, and superior redox capacity, thus achieving high-efficiency photocatalytic H2 evolution.
