Photocatalytic hydrogen production and pollutant degradation using a heterogeneous photocatalyst remains an alternative route for mitigating the impending pollution energy crisis. Hence, development of cost-effective environmentally friendly semiconducting materials with high solar light captivation nature is imperative. To overcome this challenge, α-MnO2 nanorod (NR)-modified MOF UiO-66-NH2 (UNH) was prepared via facile solvothermal method, which efficient toward H2 evolution oxy-tetracycline hydrochloride (O-TCH) degradation. The field-emission scanning electron microscopy (FESEM) high-resolution transmission (HR-TEM) results α-MnO2@UNH (MnU) hybrid reveals its embedded in matrix, X-ray photoelectron spectroscopy (XPS) result confirms interaction UNH moiety NRs. Additionally, outstanding separation photogenerated excitons charge-transfer efficacy are further validated by photoluminescence (PL), time-resolved (TRPL), electrochemical impedance (EIS), transient photocurrent analysis, key causes photoactivity augmentation MnU composites. MnU-2 composite shows superior O-TCH efficiency 93.23% excellent rate about 410.6 μmol h–1 upon irradiation. This study provides significant evidence favor suggested mediator-free S-scheme-adapted charge migration path, it effectively explains enhanced exciton leading to extraordinary catalytic proposed composite.

Photocatalytic degradation of oxytetracycline using ZnO catalyst

Environmental Progress & Sustainable Energy, Год журнала: 2024, Номер 43(4)

Опубликована: Фев. 23, 2024

Abstract In the present study, degradation of oxytetracycline (OTC) under ultraviolet (UV) light in presence ZnO catalyst was investigated, and optimum parameters for efficiency were determined. Different pH values, dosages, reaction times, OTC concentrations, UV lights used this study. The conditions found as follows: 4, 1 g L −1 , time 25 min, concentration 10 mg . Degradation 42.1%, 76%, 70.7%, 61.7% photocatalytic (for UV‐A, UV‐B, UV‐C) at optimal conditions, respectively. resulting products after oxidation determined To identify toxicity OTC, lowest LC 50 (50% lethal concentration) EC effective values found. ethanamine, 2‐(2,6‐dimethylphenoxy)‐ N ‐methyl‐ by‐products observed to be more toxic than OTC. Furthermore, it seen that isopropoxy carbamic acid, ethyl ester formed, whose is environmentally risky aquatic environments due their low EC50 values.
