Interesting and potentially useful macroporous materials can be made by exposing non‐aqueous emulsions, e.g., water‐sensitive metal alkoxides in formamide, to water, it is reported. The Figure shows an SEM image of a titania foam made by the addition of water to a non‐aqueous emulsion of titanium isopropoxide and isooctane. The microstructure is robust and preserved even after calcination.
