Supercritical CO₂ synthesized TiO₂ nanowires covalently linked with core–shell CdS–ZnS quantum dots: enhanced photocatalysis and stability

Abstract

The novel fabrication of CdS–ZnS QDs linked with TiO₂ photocatalyst is demonstrated. Results show that core–shell structure, covalent linking, and catalyst loading play a key role to enhance the photocatalytic activity.
