Abstract: Various metal oxide mesocrystals can be synthesized in a simple manner by a method for producing a metal oxide mesocrystal, the method comprising the step of annealing an aqueous precursor solution comprising one or more metal oxide precursors, an ammonium salt, a surfactant, and water at 300 to 600° C. Composite mesocrystals consisting of a plurality of metal oxides or an alloy oxide can also be provided.
