Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal oxide meso crystal.SOLUTION: A precursor aqueous solution containing one kind or two or more kinds of metal oxide precursors, ammonium salt, surfactant, and water is fired under conditions of 300-600°C. This makes it possible to easily synthesize various kinds of metal oxide meso crystals, thereby providing a composite type meso crystal composed of a plurality of metal oxides or an alloy oxide, and a metal meso crystal in which a metal oxide meso crystal has a mean width of 0.01-1000 μm and a mean pore diameter is 2-60 nm.SELECTED DRAWING: None 【課題】金属酸化物メソ結晶の製造方法を提供する。【解決手段】１種又は２種以上の金属酸化物前駆体、アンモニア塩、界面活性剤、及び水を含む前駆体水溶液を、３００〜６００℃の条件下に焼成する。様々な金属酸化物メソ結晶を簡便に合成できる。また、複数の金属酸化物、又は合金酸化物からなる複合型メソ結晶。金属酸化物メソ結晶の平均幅が０．０１〜１０００μｍであり、又、平均細孔径が２〜６０ｎｍである金属メソ結晶。【選択図】なし
