摘要：

Pt nanowires are prepared in mesoporous FSM-16 by photoreduction of H2PtCl6, while H-2-reduction of H2PtCl6/FSM-16 at 673 K gives Pt nanopatrticles in FSM-16. The Pt nanowires and nanoparticles are characterized by physicochemical methods such as XAFS, TEM, XRD, and XPS. The formation mechanism of the Pt nanowires and the catalytic performance in the water-gas-shift reaction are also investigated.
