【Abstract】 New pattern TiO 2/Ti films electrode have prepared by anodising as titanium alloys as stuff.XRD and SEM results indicate the film electrode is composed of anatase phase and with TiO 2 size about 45-50nm by controlling reaction conditions.The TiO 2/Ti film electrode shows a high photocatalytic activity in photodegradation of rhodamine B,at the same time,it can increase the efficiency of photocatalytic by external definite voltage.更多还原
