| 英文摘要 | Microporous. mesoporous hybrid ti-mcm-41(h) was successfully synthesized by the nano. cluster assembling method. gold nano. particles were prepared by the deposition. precipitation method. the samples were characterized by powder x-ray diffraction (xrd), nitrogen isothermal adsorption. desorption, fourier transforminfrared (ft-ir) spectroscopy, diffuse reflectance uv-vis (dr uv-vis) spectroscopy, transmission electron microscopy (tem) and inductively coupled plasma emission spectrometry (icp-aes). the catalytic performance of the gold nano. particles was evaluated by the direct gas phase epoxidation of propylene using hydrogen and oxygen. results revealed that the ti. mcm. 41(h) had a typical mesoporous mcm-41 structure. the results also suggested that isolated ti(iv) was introduced into the siliceous framework of the support material. superior catalytic performance was obtained with the gold catalyst supported on ti. mcm. 41(h) in which the ti/si molar ratio was 1%. propylene conversion reached 5.4% at the initial 30 min with 74.2% propylene oxide (po) selectivity and produced rate 73.1 g.h(-1).kg(-1). the conversion and po selectivity were 4.9% and 67.3% after running 330 min on streamat 423 k. |
