The oxide and reduce potential and the dopant concentration . the experiments of degradation methyl blue a1so showed that the photocatalytic activity could be greatly improved with vzos - loaded tio2 , maybe that loading v2o5 would accelerate the electron captured and charge transferring , change the samp1e surface hydrophilic and absorption 纳米tio _ 2 - v _ 2o _ 5复合光催化剂对次甲基蓝的降解实验表明，复合v _ 2o _ 5后tio _ 2可以加速电子捕获和电荷迁移速率，改变了样品表面吸附亲合力，使降解效率相比纯tio _ 2有很大提高。
