This research focuses on the synthesis of NiFe2O4/Chitosan-PVA/ZnO composite as a photocatalyst in tetracycline degradation. ZnO acts as a catalyst and is combined with NiFe2O4 to reduce the band gap of ZnO. Chitosan-PVA in the composite acts as a barrier between ZnO and NiFe2O4 to preventing photodissolenscence. The synthesized composite NiFe2O4/Chitosan-PVA/ZnO is characterized using VSM, XRD…
