摘要：

Pt, Rh, Pt-Rh, and Pt-Pd nanowires were synthesized by a photoreduction method using mesoporous silicas FSM-16 and HMM-1 as templates. The metal nanowires occluded in the mesopores were characterized by several physicochemical methods. The TEM and XAFS studies have demonstrated that the nanowires grow by the reduction of Pt precursors on small nanoparticles initially formed in the mesopores. Dissolution of silica matrix with HF separated the nanowires that are stabilized in solutions. The Pt nanowires and nanoparticles in FSM-16 were used as catalysts in water-gas-shift reaction and hydrogenolysis of butane. It is noteworthy that Pt nanowire/FSM-16 shows higher activities than Pt nanoparticle/FSM-16.
