Ordered mesoporous MgO films are synthesized via micelle‐templating for the first time. The problems of low melting points, insolubility and excessive crystallization of the metal oxide precursors are overcome by synthesizing in‐situ a magnesium nitrate‐citric acid complex. The stepwise thermal transformation into magnesium carbonate and then MgO was studied as well as the evolution of the mesopore structure.
