Abstract

Two layers of mesoporous silica with orthogonally stacked and oriented mesopore cylinders were observed by transmission electron microscopy. Analysis showed orthogonally stacked mesostructures with different pore sizes depending on the position. Furthermore, the adsorbed dye inside the mesopores suppressed structural collapse, and elution occurred from the top layer.
