Facile preparation of ellipsoid-like MCM-41 with parallel channels along the short axis for drug delivery and assembly of Ag nanoparticles for catalysis

Abstract

In this study, ellipsoid-like MCM-41 nanoparticles with parallel channels along the short axis were prepared by using a surfactant mixture of cetyltrimethylammonium bromide (CTAB) and sodium dodecylbenzenesulfonate (SDBS) as a template. This particulate system shows high drug loading capacity, a sustained release profile and efficient assembly of Ag nanoparticles for 4-nitrophenol reduction.
