title: Pt, Rh and Pt-Rh nanoparticles on modified single-walled carbon nanotubes for hydrogenation of benzene at room temperature.
abstract: Nanometer-sized Pt, Rh, and bimetallic Pt-Rh particles can be deposited on surface of phenylacetic acid functionalized single-walled carbon nanotubes (SWCNTs) by a microemulsion method. The SWCNT-supported metallic nanoparticles show much greater catalytic activities compared with commercially available carbon-supported Pt and Rh catalysts for hydrogenation of neat benzene under mild experimental conditions. The bimetallic Pt-Rh nanoparticle catalyst synthesized by this method shows an enhanced activity relative to individual SWCNT-supported Pt and Rh nanoparticle catalysts. The SWCNT-supported metal nanoparticle catalysts can be recycled and reused at least five times without losing their activity. The hydrogenation reactions performed under our experimental conditions would not affect the pi-pi stacking holding phenylacetic acid on SWCNT surface.
