The properties of supported non-noble metal particles with a size of less than 1nm are unknown because their synthesis is a challenge. A strategy has now been created to immobilize ultrafine non-noble metal particles on supports using metal-organic frameworks (MOFs) as metal precursors. Ni/SiO2 and Co/SiO2 catalysts were synthesized with an average metal particle size of 0.9nm. The metal nanoparticles were immobilized uniformly on the support with a metal loading of about 20wt%. Interestingly, the ultrafine non-noble metal particles exhibited very high activity for liquid-phase hydrogenation of benzene to cyclohexane even at 80 degrees C, while Ni/SiO2 with larger Ni particles fabricated by a conventional method was not active under the same conditions.
