Abstract

original image

A simple solution: In the simple approach to silica films with perpendicular mesochannels presented herein, the substrate is immersed into a Stöber solution in which the silica precursors are hydrolyzed, cross-linked by an ammonia catalyst, and assembled with a surfactant on the substrate to form hexagonal mesostructures perpendicular to the substrate surface.
