摘要：
A silica-decoration methodology was applied to a Ni-Zn alloy for developing active and selective acetylene semihydrogenation. Ni-Zn alloy nanoparticles on SiO2 were further decorated by additional silica, which significantly increased the acetylene conversion (15-97%) without lowering the ethylene selectivity (ca. 80%) at 200 degrees C.
