Al-doped zinc oxide（AZO） and Ga-doped zinc oxide（GZO） thin films with the same doping concentration（3.6 at%） were deposited on glass substrates at room temperature by direct current（DC） magnetron ***,we comparatively studied the doped thin films on the basis of their structural,morphological,electrical,and optical properties for optoelectronic *** thin films exhibited excellent optical properties with more than 85%transmission in the visible *** GZO thin film had better crystallinity and smoother surface morphology than the AZO thin *** conductivity of the GZO thin film was improved compared to that of the AZO thin film：the resistivity decreased from 1.01×10^-3 to 3.5×10^-4 Ω cm,which was mostly due to the increase of the carrier concentration from 6.5×10^20 to 1.46×10^21cm^-*** results revealed that the GZO thin film had higher quality than the AZO thin film with the same doping concentration for optoelectronic applications.

Pt@g-C3N4/CeO2photocatalyst was prepared by calcination of g-C3N4/CeO2mixture followed by impregnating Pt. Under the irradiation of visible light with the presence of water vapor at room temperature, Pt@g-C3N4/CeO2showed significant performance for remediation of NOx. The deNOxmechanism was studied by modified in-situ FTIR. The results proved that NO was prone to adsorb on the surface of Pt@CeO2and oxidized to nitrite for storage. Then, the photoinduced hydrogen on Pt@g-C3N4component could diffuse into the vicinity of nitrite through the spillover effect of Pt and reacted with nitride to produce N2and H2O.

Uniform CeVO4 nanowires with diameter of about 25 nm were synthesized by the water-in-oil microemulsion method at room temperature from cerous chloride, sodium orthophosphate, sodium chloride, cyclohexane, Triton X-100 and cetyltrimethyl ammonium bromide （CTAB）. The crystal structure and morphology of the nanowires were characterized by XRD and TEM, respectively. The UV-vis absorption was detected by UV-vis spectrophotometer techniques. The results showed that as-prepared nanowires with the hexagonal phase have obvious quantum confinement effect and semiconductor characteristics. Little sodium chloride could play a positive role on the formation of CePO4 nanowires at room temperature. The size of the nanowires can be controlled through the joining of sodium chloride.
