英文摘要 | a series of modified ni-zn bimetallic catalysts were prepared by depositing different kinds of 4 wt% metals (ir, pt, au, cu, ag) on the ni-zn-al hydrotalcite (nzah) and tested in the selective hydrogenation of acetylene. the activity was enhanced by 3-fold over the 4 wt% au/nzah, meanwhile, the yield of c2h4 was also increased more than 4 times compared with the nzah. characterization by means of h-2-tpr, xrd, sem, and tem revealed that au was highly dispersed on the catalyst, and the ternary au-ni-zn alloy was formed during the h-2 reduction at 500 degrees c. doping au in ni-zn bimetallic catalyst weakens the adsorption of acetylene and also hinders the coke deposition on the catalyst, which leads to the enhanced activity in acetylene hydrogenation. |
