过渡氧化物纳米粒子的制备及其催化性能研究

摘要

过渡态氧化铱(Ⅳ)纳米粒子由三水三氯化铱与氢氧化钠通过固相法在室温下制得.制备出的氧化铱(Ⅳ)纳米粒子具有活性高,粒径小,稳定性好等优点.本文的纳米催化剂可用氢气球氢化喹啉类化合物,催化性能优越,产品转化率可达到95％以上.与此同时,制备的氧化铱(Ⅳ)纳米粒子催化剂可回收循环利用且具有很好的催化活性.%The transient oxidation iridium (Ⅳ) nanoparticles are made at room temperature by the solid phase method of trihydrated iridium and sodium hydroxide. It has the advantages of high activity, small particle size and good stability. The nano-catalyst in this paper can be used to Hydrogenation quinoline compounds, the catalytic performance is superior, the conversion of products can reach more than 95 ％. At the same time, the preparation of iridium (Ⅳ) nanoparticles catalyst can be recycled and has good catalytic activity.
