Fabrication of Metal Nanostructures in Mesoporous Silicas.

摘要

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 dispensed 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.
