Photocatalytic Activity of Nanosized TiO2 Enhanced by co-doping with Fe3+ and Nd3+ Ions傅平丰,赵卓,王敬欣摘 要:In this study, nanosized TiO2 co-doped with Fe3... (MB) solution. The results indicated that TiO2 crystalline size was reduced and phase transformation of anatase to rutile was suppressed as the content of doped Nd3+ ion increased in the co-doped TiO2......

, Xiangtan University, Xiangtan 411100, China) Abstract: F and Cu co-doping TiO2 hollow microspheres were synthesized via steam heat method, using tetrabutyl orthotitanate as Ti source, hydrofluoric... degradation of cationic blue was used as a probe reaction to evaluate their photocatalytic activity. The results indicate that the F and Cu co-doping TiO2 hollow microspheres are anatase phase structure, Cu2......
of fluorescent lamp. The results indicate that Pr and N co-doping efficiently restrains the growth of TiO2 crystalline size. The adsorption edge of visible light is red shifted, the phosphorescence fluorescence (PL) spectra intensity of sample is evidently depressed, and the photocatalytic activity of the sample greatly increases, because of the synergic effect of the co-doping ions. The degradation......
