A strong hydrogen bond (H-bond) exists in a binary mixture of dye aqueous solution (e. g. methylene blue, MB) with a ketone (e. g. acetone, AC) contamination. According to the limited literature and our preliminiary results, the MB in an MB/AC binary solution is not degradable (the decolorization percentage is < 10%) within 30-40 min of the initiated oxidation process. In this study, we use a Bi-doped TiO2 electro-catalytic system, Fenton system, photo-Fenton, and Bi-doped or non-doped TiO2 photocatalytic systems as the oxidation systems for MB/AC binary aqueous solutions. The results show that highly Bi-doped TiO2 can be used as an effective catalyst in electro-catalytic systems to realize an H-bond stabilized dye solution with ketones; the decolorization percentage of electrocatalytic systems is almost 60% within 30 min, which is better than that of 20% for the Fenton and photo-Fenton catalytic oxidation systems.
