Ru nanoparticles were synthesized from RuCl3 under mild H2 pressure within a suspension of cellulose nanocrystals. X-ray photoelectron spectroscopy and transmission electron microscopy revealed that the small Ru(0) nanoparticles (3.3 ± 1 nm) were deposited onto their cellulosic support. This hybrid proved to be a highly efficient arene hydrogenation catalyst operational at 4 bars and room temperature.
