摘要: Well-dispersed Ni-CeOx nanoparticles grown on carbon nanotubes (CNTs) were successfully synthesized via a simple one-step co-reduction method. The structure and properties of the catalysts investigated by XRD, XPS, SEM, TEM ICP-OES. Among prepared catalysts, Ni1-(CeO1.8)0.5/CNTs exhibited highest catalytic activity, with 100% hydrogen selectivity 80 molH2 mol Ni −1 h−1 generation rate (HGR) for from hydrazine under 1.0 M NaOH solution at 343 K. This superior performance might be attributed to smaller sizes amorphous states Ni species in Ni1-(CeO1.8)0.5/CNTs, as well close attachment NPs CNTs.
