)09-3640-05 Effects of Ni-Zn co-doping on dielectric properties of (Mg0.95Ca0.05)TiO3 ceramics ZENG Feng, ZHOU Hongqing, XIE Wentao, HUANG Fang (State Key Laboratory of Materials-Oriented Chemical.... The effects of Ni-Zn co-doping on the phase formation, the microstructures and dielectric properties of (Mg0.95Ca0.05)TiO3 ceramics were investigated. The results show that the formation of second......
="ChDivSummary" name="ChDivSummary">Nitrogen(N) and phosphorus(P) co-doped anatase TiO2 nanosheets were realized by low-temperature self-doping N–TiO2 followed by high-temperature P doping with foreign... photocatalytic properties are attributed to two factors. On one hand, N–P co-doping can effectively reduce band gap of TiO2from 3.20 to 2.48 e V,leading to an enhancement of the absorption in visible......
cases,Ce and Ti co-doping is more beneficial to improving of the coercivity than Ti single doping in Nd-Fe-B alloys.With further Ce addition,magnetic properties deteriorate due to the formation of CeFe2......
peak at 542 nm attributed to the 5D4→7F5 transition of Tb3+, which was enhanced significantly(about 45 times) by the co-doping of Ce3+, indicating that there occurred an efficient energy transfer from......
was investigated by photocatalytic degradation of methyl orange(MO).The results showed that boron and lanthanum ions incorporated into the lattice of BiVO4,and co-doping led to more surface oxygen vacancies...Lanthanum and boron co-doped BiVO4 with enhanced visible light photocatalytic activity for degradation of methyl orange王敏,车寅生,牛超,党明岩,董多College of Environmental and Chemical Engineering,Shenyang......

by dipping-lift process. The photodegradation of formic acid solution(1%) on TiO2 film with different dopants was studied. The results show that the Fe3+/La3+-TiO2 film with the appropriate doping concentration (1%Fe3+, 0.5%La3+ (mole fraction)) has better photocatalytic activity. The roles and mechanism of doping Fe3+, La3+ and co-doping Fe3+/La3+ ions were studied by XRD and absorption spectra......
