纳米TiO_2/聚苯胺复合膜的制备及其光催化降解苯酚

Preparation of Complex Film of Nunocrystalline TiO2/PoIyanline and Photocatalytic Degradation of Phenol

采用1mol.L^(-1)硫酸作为介质,扫描速度为100mV.S^(-1),扫描电位为-0.2～0.8V,用循环伏安法在纳米二氧化钛(Nano-TiO_2)膜电极上实现了苯胺(Aniline)的电化学聚合,借助透射电镜、X射线衍射仪、红外光谱对制得的Nano—TiO_2/聚苯胺(Nano—TiO_2/PANI)复合膜进行了表征,并利用其对苯酚降解进行光化学催化,结果表明:Nano-TiO_2/PANI复合膜对苯酚的降解有较好的催化活性。

Polymerization of aniline on a nanocrystalline titanium dioxide film electrode(Nana-has been achieved in a medium of 1mol. L-1 sulfuric acid with scanning voltage -0.2-0. 8V at the rate 100mV. S-1. The complex film was charactered by means of TEM, XRD and FT-TR. The complex film was utilized to photocatalystic degrade phenol and the result shows that the Nano - TiO2/PANI has favorable catalytic effect on the photocatalytic degradation of phenol.
