Sonochemical synthesis of CuSnO3 NPs as a photocatalyst for efficient degradation of MB and environmental remediation

Abstract

In this study, the synthesis, characterization, and application of CuSnO₃ nanoparticles (NPs) are presented as an efficient photocatalyst for the degradation of methylene blue (MB) under visible irradiation. The CuSnO₃ NPs were synthesized via a facile sonochemical method for the first time and characterized using various techniques to investigate their crystalline structure, elemental composition, morphology, and optical properties. The results demonstrated a significant degradation efficiency, with ∼80 % of MB being degraded. This high efficiency is attributed to the optimal energy band gap of CuSnO₃ NPs, which facilitates effective photon absorption and the generation of reactive oxygen species. Furthermore, the stability and reusability of the photocatalyst were investigated. The sonochemically synthesized CuSnO₃ NPs retained their activity with negligible loss in performance, highlighting their robust stability and potential for long-term application in wastewater treatment, outperforming many catalysts synthesized by conventional routes in long-term performance metrics.
