Abstract

Catalytic aqueous suspensions of Rh(0) nanoparticles have been easily prepared by chemical reduction of rhodium trichloride with sodium borohydride in dilute aqueous solution of THEA16Cl. First, the molecular ratio R = THEA16Cl/Rh has been optimized to avoid aggregation and to provide an efficient stabilization. As previously described for HEAX-Rh nanoparticles, a molar ratio of 2 was used to maintain stable THEA16Cl-Rh nanoparticles.
