제목 Operational Parameters Optimization of Naphthacene-based Antibiotic-enhanced Photocatalytic Degradation over Hierarchical CdWO4-decorated Reduced Graphene Oxide
초록 The search for high-efficient photocatalyst for decontamination of organic pollutants from wastewater or natural water remains a great challenge. In this study, a new photocatalyst consisting of reduced GO/CdWO4composite was synthesized by a wet chemical process and utilized for the degradation of a naphthacene-based antibiotic (tetracycline(TC))under solar-light exposure. The Box–Behnken four-level experimental design was employed to find the maximum yield of photocatalytic degradation and optimize the process variables. The synthesized hierarchical structure showed a narrow band gap of 2.46 eV, indicating their availability as a robust visible-light-driven photocatalyst for degradation of conjugated aromatic compounds.The optimal conditions for the complete TCdegradation are found to be: irradiation time:60 min, catalyst dosage of 0.216 g L-1,[TC]0of 13.54 mg L−1, and pH5.8. The kinetic analysis confirmed that the degradation of TC follows the Langmuir–Hinshelwood kinetic model.
