| 1 | Towards Improvement of Photovoltaic Performance of Aqueous Dye-sensitized Solar Cells by Tungsten-doped Mesoporous Nanobeads TiO_2 Working Electrode显示文摘Tungsten doped(W-doped) TiO_2 mesoporous nanobeads, possessing high surface area and superior scattering effect, were used for photoanode preparation. The W-doping would induce a positive shift of the TiO_2 conduction band, and enhance the driving force for electron injection and collection efficiencies. The electrochemical impedance spectra indicated a retarded charge recombination and increased electron diffusion length after W-doping. By fine-tuning the W-doping concentration to 0.25%, aqueous DSCs produced a significant improved the open circuit voltage of 712 mV and a short circuit current of 7.05 mA·cm^(-2), leading to an overall increased power conversion efficiency of 3.40% at 1 000 W·m^(-2) simulated irradiation, which is roughly 25% enhancement compared to that without W-doping photoanode. | 郭言荣 ZOU Tingting CHENG Qin JIAO Binqing 张晓俐 | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，1： | 1 |
| 2 | In Situ Growth of Vanadium Oxide on Reduced Graphene Oxide for the Low-Temperature NO-SCR by NH3显示文摘The vanadium oxide/reduced graphene oxide (V2O5/rGO) composite catalyst which determined the selective catalytic reduction activity (SCR) of NO with NH3 was prepared by a simple solvothermal method. The physicochemical properties of the catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman, X-ray energy spectrometer (XPS) and N2 sorption isotherm measurement (BET). Results of NH3-SCR showed that the NO conversion of V2O5/rGO catalyst could reach 54.3% at 100 °C. And the removal of NO increased to 74.6% when the temperature was up to 220℃. By characterizing the microstructure and morphology of the V2O5/rGO catalysts prepared by in-situ growth and mechanical mixing methods, it was further shown that V2O5 nanoparticles were highly dispersed and in situ growth on the rGO surface. Based on X-ray energy spectrometer, V2O5/rGO catalyst had good low temperature denitrification performance due to the chemical adsorption oxygen and low-valent vanadium oxide contained in V2O5/rGO catalyst, which was beneficial to the redox reaction between V2O5 and graphene. | 李美颜 QI Yanyuan 金伟 JIAO Binqing ZHAO Jie | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，3： | 0 |
