英文摘要a series of rh-mn-li/sio2 catalysts were prepared by the impregnation of a silica support with solutions containing metal precursors with different amounts of urea. catalyst performance was investigated by the hydrogenation of carbon monoxide. the catalysts were characterized by x-ray diffraction, transmission electron microscopy, hydrogen chemisorption, diffuse reflectance ultraviolet-visible (dr uv-vis) spectroscopy, and thermogravimetric analysis. the results revealed that the amount of urea had a significant effect on the particle size of rh, which increased from approximately 2-5 nm with the increase in urea loading from 0 to 2.0 wt%. dr uv-vis spectra indicated that the increase in the rh particle size with increasing urea loading might be attributed to the coordination of rh3+ with urea or its derivatives during calcination. at a urea loading of 1.0 wt%, the particle size of rh was 3.7 nm, and the space time yield of c2+ oxygenates reached a maximum of 560.0 g kg(-1) h(-1).
