In this work, novel CeO2/CoWO4 hetero structured nanocomposites (NCs) was synthesized via a hydrothermal method. X-ray diffraction (XRD), high-resolution transmission electron microscopy(HRTEM), UV-VisDRS and photo luminescence (PL) spectroscopy were categorized herein to gain the crystal structure, deep morphology, optical assets, and charge separation of the as-produced photocatalysts (PCs)respectively. Related by the pristine CoWO4,CeO2 and CeO2/CoWO4 photocatalyst was considered by enriched activity of them ethylene blue (MB)aqueous dye photodegradation under visible light exposure. Chiefly, the photodegradation efficacy of as-attained CeO2/CoWO4 photocatalyst exposed the premier decomposition ratio (92.5%) of MB dyein105 min among all samples, which was noticeably 1.8 and 2.2 folds over the pristine CeO2 (43 %) and CoWO4(60 %), separately. Likewise, the CeO2/CoWO4 PCs sustained satisfactory activity even after 4sequentialrecycling runs, signifying its great photocatalytic steadiness and robustness. Hence the ensuing superior PCs preferred the further efficient charge (e−-h+) separation, solid visible light fascination, and worthy interfacial energy transfer leads amid CoWO4 and CeO2nanoparticles (NPs).A likely mechanism liable for photodegradation was eventually projected. The synergistic things of antibacterial motion via CeO2/CoWO4 NCs were probed by the weld diffusion scheme. Thus, effort finding deals with a novel avenue for the growth of stable and proficient visible-light active PCs for environmental purification.
