One-pot synthesis of a TiO2–CdS nano-heterostructure assembly with enhanced photocatalytic activity

Abstract

An unprecedented morphology of a titanium dioxide (TiO₂) and cadmium sulfide (CdS) self-assembly obtained using a ‘truly’ one-pot and highly cost effective method with a multi-gram scale yield is reported here. The TiO₂–CdS assembly, comprising of TiO₂ and CdS nanoparticles residing next to each other homogeneously self-assembling into ‘woollen knitting ball’ like microspheres, exhibited remarkable potential as a visible light photocatalyst with high recyclability.
