| 摘 要： | 进行了微弧氧化法在制备TiO2光催化剂中的应用研究,考察了各工艺条件对制备的TiO2光催化剂降解甲基橙的活性影响,发现以0.11 mol/L磷酸为电解液,放电5min制备的催化剂活性最佳,120min内使甲基橙脱色率达49%.通过超声处理和重复使用对催化剂进行考察,发现其表现出良好的稳定性.表征结果表明文中以钛为阳极进行微弧氧化,其表面形成的陶瓷层为多孔的、纳米级的锐钛矿型的TiO2.

| Abstract: | The effect of the technological condition of micro - arc oxidation on the photocatalysis activity of of prepared TiO2 has been studied. The decolorizing rate of methyl - orange in water is up to 49% in 120 min with the TiO2 catalyzer prepared by micro - arc oxidation in the electrolyte of 0.11 mol/L phosphoric acid for 5 min. The catalyzer has been proved to be steady with ultrasonic process in repeated using. It has been proved that the ceramic coating on the Ti anode formed by micro -arc oxidation is porous and nanometer anatase. |
