摘    要:应用电化学阳极氧化法制备Ti上多孔状纳米晶TiO2薄膜,以及不同Fe^3 离子掺杂量的二氧化钛薄膜.研究了Fe^3 离子掺杂对二氧化钛薄膜吸收光谱和光催化活性的影响,发现Fe^3 的掺杂使薄膜的吸收带边发生红移,在可见光照射下其光催化活性也有一定的提高.

关 键 词:Fe^3+  光催化活性  光电化学  离子对  催化性能  薄膜  离子掺杂  膜吸收  可见光照射  二氧化钛

Abstract:Photo-catalytic titanium dioxide film in nano crystalline has been prepared by electrochemical oxidation process and adding different amount of ferric ion into the electrolyte during the anodic oxidation.The effects of Fe~(3+) dopen on absorption spectra and photo-catalytic of the titanium dioxide films have been studied. It shows that the Fe~(3+) dopen caused the red shife of the absorption edge for the incoming light and exhibited the improved photocatalytic reactivity.
Keywords:Electrochemical oxidation  Nano titanium dioxide film  Fe~(3+) dopen  Photocatalysis
