摘要
Platinum nanoparticles, nanorods, and nanonetworks were fabricated in mesoporous silica MCM-48. Investigations including transmission electron microscopy (TEM) with electron diffraction, powder X-ray diffraction (PXRD) with Rietveld analysis, and extended X-ray absorption fine structure analysis (EXAFS) suggest the crystal growth mechanism, packing arrangement, and oxidative capability of confined nanostructured metal in the MCM-48 host with a three-dimensional channel structure and cubic Ia3d symmetry.
