用阳极氧化法,通过向H2SO4电解质溶液中添加钨酸钠,在基体钛表面原位生成复合WOx-TiO2/Ti陶瓷膜。通过SEM、EDS、XRD对陶瓷膜进行表征,并对其光催化活性进行测试。结果表明:复合陶瓷膜表面粗糙多孔,以锐钛矿型TiO2为主晶相,同时检测出含有少量WO3、WO2等混合晶相,当掺入Na2WO4浓度为1 mmol/L时制备的复合陶瓷膜在120 min时对腐殖酸的可见光催化效率提高了27.8%。 Anodic oxidation was used to produce in-situ composite WOx-TiO2 / Ti ceramic membranes on the substrate surface by adding sodium tungstate to the H2SO4 electrolyte solution. The ceramic films were characterized by SEM, EDS and XRD, and their photocatalytic activity was tested. The results show that the surface of the composite ceramic membrane is rough and porous with anatase TiO2 as the main crystalline phase, and a small amount of mixed crystal phases such as WO3 and WO2 are detected. When mixed with Na2WO4 concentration of 1 mmol / L, the composite ceramic membrane The visible light photocatalytic efficiency of humic acid increased by 27.8% at 120 min.
