【Abstract】 Solvent-stabilized palladium nanoparticles were prepared in tetraethylene glycol, the nanoparticles so-prepared were narrowly dispersed with dimension of ()2~3 nm. Tetraethylene glycol functionated as a solvent, reactant and a stabilizer herein. The palladium nanoparticles were used as a catalyst for hydrogenation of cyclohexene, the catalytic activity was two times higher than that of the conventional Pd/C catalyst.更多还原
