Synergistic purification of chromium-containing wastewater via adsorption-photocatalysis induced by multiple defect-containing CuS/Cv-CNNs

A defective CuS/Cv-CNNs heterojunction is proposed, which promotes its adsorption and photodegradation of Cr( vi ) through the synergistic effect of multiple defects, thus accelerating the removal of high concentrations of Cr( vi ).
