Abstract
Designing a novel photocatalyst for the degradation of persistent dyes in water is of immense significance considering the harmful impacts of untreated textile and dye industry waste water. Bulk scale treatment requires simple and low-cost installation methods with good efficiency and Photocatalysis offers a promising solution. This paper presents a dependable design of a photocatalyst for the treatment of dye-contaminated water. Nitrogen and Carbon doped CoSb2O6 are prepared for improved photoresponse and photocatalytic activity. The paper briefs synthesis of the oxygen-deficient parent CoSb2O6 catalyst by metathesis method, followed by doping with nitrogen and carbon, characterization by XRD, UV–Vis DRS, XPS, SEM-EDX, and the performance of as-prepared samples for photodegradation of Rhodamine B (RhB) dye. The scavenger experiments were carried out to establish the active species involved in the decomposition of Rh B. Interestingly, the doped samples have shown remarkable photodegradation activities of up to 99% in 120 mins under visible light irradiation.
