A special room‐temperature ionic liquid , 1‐hexadecyl‐3‐methyl‐imidazolium chloride, is used as a template to prepare monolithic super‐microporous silica with lamellar order (monolith in Figure) via a nanocasting technique. The silica walls of the synthesized product are arranged parallel to each other, displaying a regular structure with an interlayer distance, pore diameter, and wall system thickness of about 2.7 nm, 1.3 nm, and 1.4 nm, respectively.
