:A Relationship between phosphorus doping concentration and electronic structure in anatase TiO2 ZHENG Shu-kai1, 2, WU Guo-hao1, 2, SU Jie1, KANG Jian-nan1, LIU Lei1 (1. College of Electronic and Informational... ultra-soft pseudo-potential method based on the density functional theory. The calculated results show that with the increase of P doping concentration, the cell volume of the anatase TiO2 decreases......
that pure TiO2 and Ce-doped TiO2 powder crystallines are a mixture of anatase and rutile;the doping can retard the development of the grain size of TiO2 and decrease the diameter of TiO2 from more than 20nm of pure TiO2 to about 10 nm;the doped TiO2 can improve the light absorption of TiO2 and suitable doping content tends to move the DRS spectrum of TiO2 towards visible light, but too much doping......
that the existence of applied electric field promotes the phase transformation from anatase to rutile. Studies on photo-catalytic degradation show that the photo-catalytic activity of TiO2 thin films in an applied...Crystallization Behavior of Anatase Films in Applied Electric Field Heating Process Zhou Feng1,Liang Kaiming2 (1.Electromechanical and Materials Engineering College, Dalian Maritime University......
