采用XRD、BET、TEM、EDX、ICP-OES和XPS等手段对纳米沸石负载铑纳米粒子（Rh/NZ-CP）进行了表征。该纳米材料含有2重量%的分布在纳米沸石上的5-20 nm金属纳米颗粒的Rh。以芳烃、硝基芳烃和烯烃为催化剂，考察了Rh/NZ-CP在温和反应条件下的催化性能。所制备的纳米催化剂可以方便地回收和重复使用多次，活性和选择性没有显着下降。该催化剂具有催化活性高、热稳定性好、可重复使用、回收简单、环境友好等优点，是一种独特的催化体系，在绿色化学中具有独特的应用前景。(C)2015 Elsevier B. V.版权所有。
Nanozeolite clinoptilolite supported rhodium nanoparticles (Rh/NZ-CP) has been prepared and characterized by a variety of techniques, including XRD, BET, TEM, EDX, ICP-OES and XPS analysis. This nanomaterial contains 2 wt% Rh in the range of 5-20 nm metallic nanoparticles distributed on nanozeolite. The catalytic performance of Rh/NZ-CP was evaluated by the hydrogenation of arenes, nitroarenes, and alkenes under moderate reaction conditions. The prepared nanocatalyst can be facilely recovered and reused many times without significant decrease in activity and selectivity. The high catalytic activity, thermal stability and reusability, simple recovery and eco-friendly nature make present catalyst as a unique catalytic system, which is particularly attractive in green chemistry.
