عنوان انگلیسی Electrochemical Photodegradation of Methyl Red using Reduction Graphene Oxide of Palm Shells Supported TiO2 Nanoparticle under Visible Irradiation
چکیده انگلیسی مقاله Contamination of dyes such as methyl red in the aquatic environment causes numerous problems. Therefore, it is necessary to develop a novel catalyst that can quickly, accurately, and effectively eliminate dye contaminants. In this study, we report the successful preparation of a new candidate electrode, the rGOps-TiO2 composite, via a hydrothermal method. Additionally, the electrodes were characterized using X-ray diffraction, spectroscopic techniques such as FTIR, and microscopic techniques such as SEM-EDX to ensure the synthesis of the prepared electrode material. The photocurrent response indicated that the rGOps-TiO2 electrode exhibited higher visible light absorption compared to the undoped rGOps. The degradation efficiency of methyl red reached 90.04% in the UV irradiation-assisted photoelectrocatalytic process, which was significantly different from the efficiency achieved under visible light irradiation, which was 94.78%. Therefore, the photoelectrocatalytic (PEC) technique based on rGOps-TiO2 showed much higher degradation efficiency for methyl red compared to the photocatalytic (PC) technique. This suggests that PEC holds promise for the treatment of dye wastewater in aquatic environments.
