Abstract
Mesoporous silicas were used as hosts for fabrication of nanostructured metals. Due to the confinement effect, densely packed metal nanowire bundles and nano-networks or highly dispersed metal nanoparticles were prepared inside the channels of mesoporous silicas by metal incorporation/reduction processes. The structure of nanostructured metals was analyzed by TEM and PXRD, and the composition was investigated by ICP-AES, EDX and EELS.
