Abstract
A plurality of mesoporous metal nitride materials may be formed by a method that includes treating with ammonia (or a related bonded nitrogen and hydrogen containing reducing material) a mixed metal oxide material that comprises at least one first metal that forms an unstable product with ammonia and at least one second metal that forms a stable product with ammonia to form the metal nitride materials that include the second metal but not the first metal. The method contemplates forming metal nitride materials, as well as metal oxynitride materials. A related method that uses a non-bonded nitrogen and hydrogen containing reducing material may yield a mesoporous metal oxide. In particular the at least one metal that forms an unstable product with ammonia comprises zinc metal.
