Fabrication of a novel separation-free heterostructured photocatalyst with enhanced visible light activity in photocatalytic degradation of antibiotics

A novel separation-free poly( N , N ′-dimethylacrylamide)–titanium dioxide/copper sulfide (PDMAA–TiO 2 /CuS) hydrogel photocatalyst with the synergistic effect of adsorption and photocatalysis has been successfully developed by a facile two-step method.
