TL;DR: In this article, a new solar-light-active noble-metal-free catalyst featuring dandelion-flower-like cobalt-phosphide embedded with CdS nanostructures grown on reduced graphene oxide (RGO)-MoS2 nanosheets was designed, and its photocatalytic hydrogen production activity was evaluated in water under simulated sunlight irradiation using lactic acid as a sacrificial reagent.
Journal ArticleDOI
Surface oxygen vacancy assisted electron transfer and shuttling for enhanced photocatalytic activity of a Z-scheme CeO2–AgI nanocomposite
TL;DR: In this article, the surface oxygen vacancies were formed on the synthesized CeO2-AgI photocatalyst, as determined by X-ray photoelectron spectroscopy, which could extend the lifetime of the charge carriers and enhance the photocatalytic activity of these catalysts for rhodamine B (RhB) dye degradation.
Journal ArticleDOI
An oxygen-vacancy rich 3D novel hierarchical MoS2/BiOI/AgI ternary nanocomposite: enhanced photocatalytic activity through photogenerated electron shuttling in a Z-scheme manner.
TL;DR: An oxygen-vacancy rich, bismuth oxyiodide-based Z-scheme 3D hierarchical MoS2/BiOI/AgI ternary nanocomposite photocatalyst exhibits promising photocatalytic activity and will be useful for potential applications in energy and environmental areas.
Journal ArticleDOI
Self-assembled macro porous ZnS–graphene aerogels for photocatalytic degradation of contaminants in water
TL;DR: In this article, a facile, green protocol for the synthesis of self-assembled 3D porous ZnS-graphene aerogels (ZnS−GAs) using vitamin-C to obtain a 3D network of supramolecular hybrid nanostructured materials was developed.
