Abstract

The sonochemical deposition of nickel nanoparticles onto the multiwall carbon nanotube aggregates leads to a uniformly distributed metal phase at high loadings and an average nickel crystal size of 4-8 nm at a 25-50 wt% nickel content. Its application enhances the catalytic activity of Ni/multiwall carbon nanotube material in the selective hydrogenation of chloroacetophenone by factors of 2-18, as compared with that prepared by traditional decoration methods.
