在己烷包水微乳液中合成的钯、铑和钯/铑纳米粒子可以直接沉积在功能化的多壁碳纳米管表面，产率很高。碳纳米管负载的钯纳米颗粒是烯烃加氢、碳-碳键形成和碳-氧键断裂反应的活性催化剂。碳纳米管负载的Rh纳米粒子是芳烃加氢的活性催化剂，碳纳米管负载的Pd/Rh纳米粒子对蒽加氢表现出异常高的催化活性。这种简单而新颖的合成技术，使碳纳米管支持monopoly和monopoly纳米粒子可能有广泛的催化应用化学合成。
Palladium, rhodium, and bimetallic Pd/Rh nanoparticles synthesized in a water-in-hexane microemulsion can be deposited directly on surfaces of functionalized multiwalled carbon nanotubes with high yields. The CNT-supported Pd nanoparticles are active catalysts for hydrogenation of olefins, for carbon-carbon bond formation, and for carbon-oxygen bond cleavage reactions. The CNT-supported Rh nanoparticles are active catalysts for hydrogenation of arenes, and the CNT-supported bimetallic Pd/Rh nanoparticles show an unusually high catalytic activity for hydrogenation of anthracene. This simple and novel synthetic technique for making CNT-supported monometallic and bimetallic nanoparticles may have a wide range of catalytic applications for chemical syntheses.
