| 英文摘要 | A series of bi-zn composite oxide catalysts were prepared by coprecipitation and used for the synthesis of phenyl isocyanate (pi) by catalytic decomposition of methyl n-phenyl carbamate (mpc). the effects of bi/zn molar ratio and calcination temperature on the phase structure and surface properties of the catalysts were investigated by x-ray diffraction, thermogravimetry, and fourier transform infrared spectroscopy. the addition of zn can make the crystalline of bi(2)o(3) change from a phase to p phase with better activity. the bi-zn precursor was almost completely decomposed at 500 degrees c to form bi(2)o(3) particles and more bi(7.65)zn(0.35)o(11.83) phase. the catalyst with a bi/zn molar ratio of 2/1 and the calcination temperature of 500 degrees c exhibited the highest activity. the mpc conversion and the selectivity for pi were 86.0% and 91.7%, respectively, which was better than the activity of bi(2)o(3) used alone. |
