Abstract

Among various emerging contaminants in water bodies, heavy metal ions and organic pollutants pose persistent damages that are hardly remediated naturally. In this regard, photocatalysis empowered by high-performance catalytic materials is a perfect fit. Herein, a series of CdS/Ce-MOF heterostructures were successfully synthesized through a facile hydrothermal method and superior photocatalytic abilities to remove Cr(VI) and Crystal violet (CV) from aqueous ambiences were unveiled. Up to 95.6% and 90% removal capabilities were reached for Cr(VI) and CV in 30 and 40 min by using as-prepared CdS/Ce-MOF heterojunctions as catalysts under solar light, and the capabilities retained high in cyclic tests. Following structural, morphological, optical, and electrochemical characterization results, the excellent photoredox ability of CdS/Ce-MOF was identified and attributed to enhanced visible light absorption ability and the improvement of charge separation ability in the heterostructure.
