| 英文摘要 | Ag/tio2 nanocomposites comprising of ag clusters on tio2 nanocrystal surfaces are of great significance in catalysts and advanced functional materials. herein a novel method to synthesize ag/tio2 nanocomposites with ag clusters under 2 nm on tio2 nanocrystal surfaces have been developed. the success of this method relies on a silver mirror reaction in toluene, which refers to the reduction of silver-dodecylamine complexes by acetaldehyde in the presence of mono-dispersed tio2 nanocrystals. the prepared ag/tio2 nanocomposites have been characterized by ft-ir spectra, uv-vis absorption spectra, x-ray diffraction (xrd) analysis, ultra high resolution scanning electron microscope (ultra-hrsem), high resolution transmission electron microscope (hrtem) and x-ray photoelectron spectra (xps). catalytic activity of ag/tio2 nanocomposites is evaluated for the reduction of p-nitrophenol (4-np) into p-aminophenol (4-ap) by nabh4. results demonstrate that ag/tio2 nanocomposites have shown an outstanding catalytic activity as well as a good stability in successive reduction of 4-np. noticeably, tof of ag/tio2-0.75 nanocomposites obtained in this work is the highest among ag based catalysts previously reported.
