| 1 | Chemical treatments of the nanocrystalline porous TiO_2 electrodes显示文摘Two types of nanocrystalline porous TiO2 electrodes were prepared by the hydrothermal and painting methods. The incident photon-to-current efficiency and photoelectrical conversion efficiency were both improved by chemical treatments of titanium tetrachloride and titanium isopropoxide. The surface roughness, quantities of adsorbed dye, photocurrent-voltage curves, IR spectra and UV-visible absorption spectra were measured, and the mechanism of chemical treatments was discussed. | ZHANG Dongshe, LIU Yao, WANG Weibo & XIAO XuruiLaboratory of Photochemistry, Center for Molecular Science, Institute of Chemistry.
