Nanoscale fabrication of metal particles and wires using mesoporous silica templates: Electronic properties and catalytic performances in PROX reaction
Pt nanowires and nanoparticles were selectively synthesized in mesoporous silica templates FSM-16 and HMM. The wires and particles were characterized by physicochemical methods. Extracted Pt nanoparticles on HOPG show Coulomb blockade phenomena in STM/STS measurements. Pt nanowires and -particles in FSM-16 shows high catalytic activity and selectivity in preferential oxidation (PROX) of CO in H-2.
