| 中文摘要 | the catalytic performance of ni/tio2 and ni-ir/tio2 catalysts in the selective hydrogenation of cinnamaldehyde (cal) has been investigated. the ni-ir/tio2 presented higher activity than the ni/tio2. here, we studied and gave some insights into the interaction between ni and ir species and the role of ir using x-ray diffraction (xrd), transmission electron microscope (tem), hydrogen temperature-programmed reduction (h-2 tpr), hydrogen temperature-programmed desorption (h-2 tpd), and x-ray photoelectron spectroscopy (xps). the size of ni particles on the ni-ir/tio2 was 10.1 nm, smaller than that (12.7 nm) on the ni/tio2. the reducibility of ni was improved by addition of a small amount of ir, as confirmed with the h-2 tpr analysis. the ni-ir/tio2 could be reduced at a temperature of 352 degrees c, which is lower than the temperature for ni/tio2 (385 degrees c); moreover, a new reduction peak appeared at 240 degrees c due to the stronger interaction of ni-ir species, which was certified by xps analysis. the h-2 tpd results indicate that the hydrogen spillover effect may occur in ni-ir/tio2. the electronic structure of the surface ni atoms was modified upon addition of ir, resulting in an enhanced activity of the ni-ir/tio2 catalyst, about four times as high as that of the ni/tio2 catalyst.
