求助大神!制备了TiO2微米管,有关光催化,电子空穴对的问题!?诸位大神请留步,小弟跪求大神解答小弟制备了一种TiO2微米管(尺寸25微米左右,壁厚1-2微米),光催化效果优于P25,且比表面积远高于P25,审稿人提出了两个问题,不知如何解答(或者本身我就写错了):Q1:The authors said that tube-like TiO2 has a relatively higher interfacial charge transfer rate than sphere-like TiO2. The mechanism should be given for the statement.Q2:The authors said that the transfer of carriers along the length of the TiO2 tubes can reduce the probability of e-/h+ recombination during the photocatalytic activity of TiO2 microtubes. Although they cite two references, the mechanism should be described.针对这两个问题,我分别对我制备的微米管和P25 测试 了PL、阻抗,想证明我的观点,但是发现两组数据都不理想。图1中,微米管强度高于P25,图2中,p25阻值更小,这完全违背我的想法。然后我做了uv-vis,数据尚可,见图3.请问,我的光催化数据很好,但是PL,阻抗很大,1)是不是因为微米级材料本身不能跟纳米级比较,2)我该如何回复审稿人这两个问题(哪些实验可以补充证明我的观点)?图1.png图2.png图3.png查看更多14个回答 . 22人已关注
