A high-dispersed Ag/Fe3O4/g-C3N4 composite photocatalyst is firstly synthesized by means of the selective photo-deposition technique.
Ag/Fe3O4/g-C3N4 showed a better photocatalytic activity, stability and reusability for degrading tetracycline.
The enhanced photocatalytic activities are ascribed to synergetic interactions of Ag, Fe3O4 and g-C3N4.
