An efficient electrochemical degradation of toxic pollutants in wastewater using BiOBr/BiVO₄ hierarchical structured...

The electrochemical degradation of alizarin red dye was studied using bismuth oxyhalide attached to bismuth vanadate nanocomposite synthesized via a simple solvothermal method. The electrochemical degradation of alizarin red dye was treated at current densities of 3 and 5 mA cm^-1 for 30 min under different supporting electrolyte mediums (NaCl and KCl). Also, the electrochemical degradation of BiOBr/BiVO₄ electrode shows higher degradation percentages of 97 and 99 for NaCl and KCl electrolyte solutions, which are higher degradation percentages than pure BiVO₄ electrode (88 and 91 for NaCl and KCl). Also, the BiOBr/BiVO₄ electrode shows 100% COD reduction during the 30th min of alizarin red dye using both NaCl and KCl electrolyte solutions. This may indicate that the prepared BiOBr/BiVO₄ electrode shows an efficient electrode material for the degradation of textile dyes.
