Metal nanoparticles on carbon nanotubes (CNTs) are expected to be efficient catalysts for several industrially important processes. Here, the successful preparation of well-dispersed Ru–CNT nanocomposites—which are subsequently demonstrated to be very active for the hydrogenation of benzene to cyclohexane—using RuCl3·H2O as the precursor is reported. The Figure shows a transmission electron microscopy image of nano- composites used four times as a catalyst.
