摘要

室温条件下通过共还原方法制得不同镍(Ni)与三氧化二钕(Nd₂O₃)摩尔配合比的镍-氧化钕(Ni-Nd₂O₃)纳米颗粒,并对制得的Ni-Nd₂O₃纳米颗粒进行表征,考察了对水合肼的降解性能。研究结果表明:在Nd₂O₃所占摩尔配合比为0.06,温度为70℃,催化反应12min条件下,制得的Ni_0.94-(Nd₂O₃)_0.06纳米颗粒对H₂的选择性达到99%;重复使用第7次时,催化反应16min,对氢气(H₂)的选择性为97%,仍具有良好的催化性能。

Abstract

Ni-Nd₂O₃ nanoparticles with different molar ratios were prepared by co-reduction method at room temperature,and the prepared Ni-Nd₂O₃ nanoparticles were characterized.The degradation of hydrazine hydrate by Ni-Nd₂O₃ nanoparticles was investigated.The results showed that when the molar ratio of Nd₂O₃ was 0.06,the temperature was 70℃,and the reaction time was 12min,the selectivity of Ni_0.94-(Nd₂O₃)_0.06 nanoparticles to H₂ was 99%.The catalytic reaction was 16min in the 7th re-use,the selectivity of H₂ was 97% and still had good catalytic performance.
