This work aimed to study the remarkable catalytic performance of fishbone (FB) doped copper (Cu) synthesized by the impregnation method for crystal violet (CV) dye’s catalytic wet hydrogen peroxide oxidation (CWPO). The catalysts (x%Cu-FB) prepared were characterized by several techniques such as the X-ray diffraction (XRD), the Fourier transformed infrared spectroscopy (FTIR), the zero point charge measurement (pHzpc), and the scanning electron microscopy (SEM) coupled by the energy-dispersive X-ray spectroscopy (EDX). In addition, this catalysis (x%Cu-FB) was employed as heterogeneous catalysts for CWPO of crystal violet dye removal using different parameters effects in particular the percentage of metallic precursor Cu, the catalyst amount, the concentration of CV dye, the hydrogen peroxide H2O2 concentration, the temperature, the pH solution. The discolorization rate efficiency was boosted from 98% for 1% Cu-FB after only 35 min of reaction with the optimum conditions namely pH=10, [CV] = 20 mg L-1, [H2O2] =0.048 mol L-1, WCu-FB = 2 g L-1 and T=50°C. Finally, it can be seen from this study that the oxidation process by a fishbone catalyst could be economical and effective in removing a large part of the textile pollutants (CV dye) existing in industrial wastewater. The scope of the study makes this method a clean alternative that fits into a perspective of sustainable development.
