摘　　要：Supported NiCu bimetallic catalysts have been produced in-situ on commercial Al_(2)O_(3)by using layered double hydroxides as precursors. The resulting catalysts show a uniform Ni and Cu distribution, thus providing good activity and selectivity in the reforming reaction of n-heptane. The catalytic performance has been found to depend on the Cu/Ni ratio, revealing the synergic catalysis between homogeneously dispersed Ni and Cu sites. The good catalysis of Ni Cu bimetallic catalysts makes it possible to partly or even completely replace Pt with NiCu bimetallic catalysts.
