Abstract
Visible light is a sustainable method for activation peroxomonosulfate (PMS). In this study, the ZnIn2S4-CoFe2O4-BC (ZIS-CFO-BC) composite photocatalytic material was synthesized by two-step hydrothermal and solvothermal methods to enhanced the efficiency of sunlight utilization. The morphology analysis revealed ZIS and CFO particles are uniformly dispersed on the Biochar (BC) surface, forming a stable heterojunction interface. A 96.39 % removal of enrofloxacin (ENR, 2 mg/L) was achieved within a 30 min period by the Vis/ZIS-CFO-BC system. According to the quenching and EPR tests, SO4•−, h+, •OH, and 1O2 were identified as the primary active species. Valence changes were observed for both Co and Fe, indicating that this is primary site for PMS activation. The findings of the cycling and co-existing ions experiments illustrate that ZIS-CFO-BC exhibits remarkable potential for various applications. This research presents a new recyclable green material that efficiently utilizes sunlight to enhance the Fenton-like system.
期刊介绍:
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
