| 英文摘要 | The surface microconstrure of tio2 photocatalyts was modified and optimized with nio-h species at low-temperature using ion quick-impregnation method. the catalysts were characterized with x-ray diffraction (xrd), and x-ray photoelectron spectrometer (xps). the results show that a small amount of ni2+ ion was deposited on the surface of tio2 in tio2-nio-h form, an appropriate amount of nio modified on tio2 photocatalyst exhibited a great improvement in hydrogen production as compared with the bare tio2, and under the optimal condition, the hydrogen production rates have increased from 1.1 mu mol.h(-1) to 241.4 mu mol.h(-1). the ni content, heat-treatment, ethanol content, ph value, and catalyst content have obvious effects on the hydrogen production rate. the results of the photoelectrochemical studies show that the appropriate amount of nio modified on tio(2)photocatalyst could produce photocatalytic reaction sites -tio2-nio-h for the photoinduced hole, and enhance the separation of the photo-induced electron-hole pairs. |
