摘要

Homogeneous Ni (x) Cu1 - x and Ni (x) Co1 - x (x = 0.90-0.99) alloys have been prepared through the coprecipitation of precursors (hydroxides or carbonates) and reduction of the precipitate. The formation of single-phase Ni (x) M1 - x alloys in all of the samples has been confirmed by X-ray diffraction. We have assessed the catalytic activity of the alloys for 1,2-dichloroethane decomposition with carbon nanomaterial (CNM) formation. The highest catalytic activity (CNM yield, 26-27 g/g(cat)) was offered by the nickel alloys containing similar to 1 at % Cu or Co. The carbon material obtained has the form of segmented submicron wires with high morphological uniformity.
