Abstract
This study explores the photocatalytic degradation of Crystal Violet (CV) using anode nanomaterials recovered from spent nickel-metal hydride (NiMH) batteries, activated by hydrogen peroxide (H₂O₂). The research focuses on the potential application of recycled perovskite-based materials, such as Lanthanum Cobalt Oxide (LaCoO₃), Nickel Oxide (NiO), and Cerium Dioxide (CeO₂), for the efficient removal of organic dyes from textile industry wastewater. Structural characterization via X-ray diffraction (XRD) confirmed the presence of crystalline phases with high crystallinity, essential for photocatalytic activity. Photocatalytic experiments were conducted under UV-A light (λ = 395 nm) at pH 5.5, demonstrating a degradation efficiency of 99.52% within 60 minutes. The reaction followed pseudo-first-order kinetics, with a significant increase in efficiency over time. These findings highlight the potential of using recycled battery materials as sustainable and effective photocatalysts for wastewater treatment, offering a promising solution to mitigate environmental contamination caused by synthetic dyes and other persistent organic pollutants.
