Book excerpt: Fine Rh nanoparticles can be deposited uniformly on surfaces of carboxylate functionalized MWNTs using the one-pot sonochemical method. The CNT-supported Rh nanoparticles show remarkably high catalytic active and are reusable for hydrogenation of arenes at room temperature. Complete ring saturation of polycyclic aromatic hydrocarbons (PAHs) can be achieved under mild hydrogenation conditions using the MWNTs catalyst that can not be done by commercially available Rh nanocatalysts (Rh- Escat 3401 ). This technique also provides a simple and rapid way of making Rh nanoparticles of different size, which allows us to study particle size effects on catalysis. Furthermore, we extended the sonochemical method to synthesize well-dispersed Pt-Rh alloy bimetallic nanoparticles on sidewalls of CNTs and studied the potentially improved activity (synergistic effect) for room temperature catalytic hydrogenation of neat benzene, neat alkylbenzenes, and PAHs.
