Preparation of BiOBr coating based on bismuth glass for water purification from organic pollutants
BiOBr photocatalytic active coatings on bismuth-boron-zinc glass carrier using acid etching synthesis were obtained. The effect of direct and indirect corrosion of the glass layer on the bonding ability of the coatings and the substrate were studied. Specially, the BiOBr photocatalytic coating obtained by acid etching after crystallization of the glass has stronger bonding ability with the glass substrate. This is because the needle-like crystal structure after crystallization can be used as a transition layer to closely combine the glass and the photocatalytic coating. In this paper, the concept of plant cultivation was introduced to explain that the coating prepared by the indirect method had a better bonding force with the substrate. This research solves the traditionally difficult recycling problem of degrading organic pollutants in the form of powder, and the preparation method is simple and suitable for industrial mass production.
