Abstract Herein, a series of CoCr 2 O 4 /wt%NiFe (CCO/wt%NFO) composites are successfully synthesized by simple solution combustion method combined with mechanical grinding techniques. The preparation CCO/wt%NFO result in an estimation its photocatalysis performance removing tetracycline hydrochloride (TC) as model antibiotic pollutants. results show that the percentage NFO mass have great influence on morphology and composites. Superior is observed CCO/25%NFO prepared at 25%. photocatalyst used removal ratio 81% for TC. generation hydroxyl radical (•OH), superoxide anion (•O − ) holes (h + largely responsible degrading TC through presence optimal operating conditions involve initial concentration pH being 50 mg L −1 = 13, respectively. Furthermore, highly reusable stable during photocatalytic process. degradation pathway, toxicity, mechanism extensively examined spectrometry, toxicity analysis, energy band theory.

Abstract A simple solution combustion method is used to synthesize spinel type MgFe 2 O 4 (MFO) and CoCr (CCO) oxides, which are combined with the mechanical mixing construct a Z‐scheme MFO/wt%CCO heterojunction, effectively degraded tetracycline hydrochloride (TC) under simulated sunlight irradiation. Various characterization techniques confirm phase structure, composition, near‐spherical morphology, ferromagnetic behavior, optical properties, photocatalytic activity of heterojunction. variety environmental experimental parameters confirmed that when optimal initial TC concentration 50 mg L −1 , catalyst content 1 g −1, pH 13, degradation percentage by MFO/75%CCO composites reached 89%. Active species verification experiments showed hole (h + ), hydroxyl radical (•OH), superoxide (•O − ) main active in reactions. Based on mass spectrometry, toxicity analysis, energy band theory, pathway, toxicity, mechanism for discussed detail.
