| titleOfInvention | A kind of preparation method of bromine oxygen bismuth thin film photochemical catalyst |
| abstract | A kind of preparation method of bromine oxygen bismuth thin film photochemical catalyst, belongs to environmental chemical engineering photocatalysis water-treatment technology field；It is characterized in that will be cleaned and dried with ethanol and acetone after bismuth plate and titanium plate polishing；KBr, ethylenediamine tetra-acetic acid is soluble in water, use 5molL ‑1 The pH value of sodium hydroxide solution regulation system is 8 ~ 9, obtains reacting required electrolyte solution；With bismuth plate as anode, titanium plate is negative electrode, is placed in electrolyte solution, and 0.5 ~ 1h is reacted under 4V voltages and magnetic agitation, and reaction temperature is controlled at 25 ~ 25.5 DEG C；The distance between two electrodes remain 5cm；After the completion of reaction, BiOBr films are formd in bismuth anode surface, then the black bismuth meal filtering that at the same time will be generated in cathode titanium plates, washing dries at a temperature of 40 ~ 50 DEG C, that is, the Bi nanoparticles with photocatalytic activity are obtained.Products obtained therefrom is used for the reactivity of the harmful hardly degraded organic substance methyl orange of trace toxic in photocatalytic degradation water, catalysis activity stabilization, high recycling rate, with actual application prospect. |
