Green Synthesis of CuO-TiO2 Nanoparticles for the Degradation of Organic Pollutants: Physical, Optical and Electrochemical Properties

CuO-TiO2 nanocomposites were successfully synthesized using the C. benghalensis plant extracts. The effect of composition CuO to TiO2 on morphological, optical, electrochemical, and photodegradation efficiency in composites was studied. SEM, XRD, UV-vis, FTIR, TGA, BET, CV used characterize these materials. XRD data reported tenorite structure anatase phase TiO2. SEM showed spherical morphologies for all NPs, also mesoporous nature, as depicted by BET. voltammogram 30/70 electrode a higher response current density compared other two samples, suggesting specific capacitance. Upon testing photocatalytic efficiencies against methylene blue (MB), ciprofloxacin (CIP), sulfisoxazole (SSX), highest degradation 94% recorded SSX nanocomposites. Hydroxyl radicals primary species responsible SSX, material could be reused once. most active has been identified OH•. From this study, it can noted that more selective toward antibiotics (sulfisoxazole ciproflaxin) dyes (methylene blue).
