Facile synthesis of a novel 0D/2D CdS/Bi₄TaO₈Br heterojunction for enhanced photocatalytic tetracycline hydrochloride degradation under visible light

Abstract

A novel visible-light-responsive 0D/2D CdS/Bi4TaO8Br nanocomposite photocatalyst was synthesized by controlling the deposited CdS quantum dots (QDs) amount on the surface of 2D Bi4TaO8Br nanoplates through a hydrothermal synthesis process....

CdS QDs decorated on 3D flower-like Sn3O4: a hierarchical photocatalyst with boosted charge separation for hydrogen production

“…This implies that Sn 3 O 4 /CdS QDs-2 has the smallest electron-transfer resistance, signifying that it has the fastest electron transfer, which is favorable for the efficient separation and transfer of carriers. 31 The recombination rate of charge carriers in the catalysts was further assessed by PL.
