Abstract

This study focuses on the photocatalytic performance of copper-doped vanadium pentoxide (Cu@V2O5) synthesized via a hydrothermal method for environmental remediation. Structural and morphological characterizations confirmed successful Cu incorporation without secondary phases, resulting in quasi-spherical nanoparticles with a narrowed band gap of 2.33 eV. The adsorption followed by photocatalytic activity was evaluated using methylene blue (MB) degradation under visible-light irradiation at a high initial dye concentration (100 ppm). Cu@V2O5 achieved 74% MB removal, with a pseudo-first-order rate constant of 0.0018 min⁻¹. The material also exhibited moderate colloidal stability and strong surface interaction with cationic dyes. These findings highlight the role of Cu doping in enhancing visible-light activity and surface properties of V2O5, making Cu@V2O5 a promising candidate for wastewater treatment applications.
