Deposition of thin mesoporous silica films on glass substrates from basic solution

Transparent thin (ca. 100 nm) films of silica–surfactant mesostructured materials were deposited on borosilicate glass plates and soda-lime glass tubes from aqueous solutions containing tetraethoxysilane, alkyltrimethylammonium chloride, ammonia, and methanol. By calcination in air, the films became mesoporous (BET surface area of 700–900 m2 g−1) with pore diameter 2.0–2.8 nm.

Transparent films with a thickness of ca. 100 nm were deposited on glass substrates from aqueous solutions containing tetraethoxysilane, alkyltrimethylammonium chloride, methanol, and ammonia.Figure optionsDownload high-quality image (39 K)Download as PowerPoint slide
