英文摘要The palygorskite supported platinum catalysts, pt/pal(i), pt/pal(ii), and pt/pal(iii) were prepared by different reduction methods (ethanol-isopropanol, h-2, and nabh4), and exhibited different catalytic properties for the hydrogenation of para-chloronitrobenzene (p-cnb). over the pt/pal(ii) catalyst the selectivity of para-chloroaniline (p-can) reached 100% and the hydrodechlorination reaction was fully suppressed during the complete conversion of p-cntb. superior selectivities of 99.7% and 99.9% for p-can were also obtained over pt/pal(i) and pt/pal(iii) catalysts, respectively, although the dehalogenation reaction was not completely avoided. pt/pal(i) was the most active catalyst with a turnover frequency (tof) of up to 27010 h(-1). pt/pal(ii) and pt/pal(iii) catalysts showed slightly lower activity with a tof of 1.7193 and 24871 h(-1), respectively. these excellent catalytic properties are attributed to the effects of pt particle size and the palygorskite support, which was confirmed by transmission electron microscopy (tem) images and x-ray diffraction (xrd) patterns of the catalysts as well as fourier transform infrared (ftir) spectra of the palygorskite.
