In order to solve the transmission system problems of Flashover, Ni2+ doped TiO2 thin film and pure TiO2 thin film were prepared by sol-gel method. The crystalline phase and morphology were characterized by XRD and AFM, and static contact angle measurement was employed to estimate the wettability of prepared films. The results indicate that a small amount of Ni2+ doped TiO2 thin film makes hydrophilicity...
For the sake of improving the self-cleaning performance of the ceramic insulator, TiO2 thin films and Ni2+ doped TiO2 thin films were prepared by sol-gel method. The crystalline phase and morphology was studied by analyzing XRD and AFM. The film's photocatalytic property was tested according to degradation of methyl orange solution. The results indicate that the film photocatalytic property decreases...
Uniform anatase-type titania (TiO2) nanoparticles were prepared by controlling gelation pH during the sol-gel process. Particle size of the anatase TiO2 was increased from ca. 7 to 23 nm with the pH increasing from 2 to 9. When pH value was 10, particle morphology showed spheroids and square shapes because of the formation of an anatase phase and hydrogen titanium oxide. Optimal preparation condition...
Bi0.9Ho0.1FeO3 ceramic is prepared by sol-gel method. We investigated the effect of Ho element doping in the BiFeO3. We studied the microstructure, morphology and ferromagnetism for Bi0.9Ho0.1FeO3 ceramic by XRD, SEM and SQUID. It shows that Bi0.9Ho0.1FeO3 ceramic exhibits single phase of perovskite structure. The c/a rate is elevated from 1 to 1.009 with respect to BiFeO3. The grains of Bi0.9Ho0.1...
