    • A manufacturing method of zinc-comprising mixed metal oxide is provided to form uniform particles by using a distributed system and to manufacture method of producing a catalytic of the mixed metal oxide containing a zinc of which an average diameter mostly is less than 200 nm. A mixed solution containing a metal precursor and a molding material is manufactured. The metal precursor is made of one or more materials and a zinc precursor. The one or more materials are selected from chrome precursor, aluminum precursor or a barium precursor. The coprecipitation material is manufactured by injecting precipitation agent into the mixed solution. A zinc-comprising mixed metal oxide of a chemical formula 1 (Zn_a-Cr_b-Al_c-Ba_d-O_e) is manufactured by drying and plasticizing the obtained coprecipitation material. In the chemical formula 1, a is a molar ratio of a Zn atom, B is a molar ratio of a Cr atom, C is a molar ratio of an Al atom, D is a molar ratio of a Ba atom and E is a molar ratio of an O atom.
    • 提供含锌混合金属氧化物的制造方法,通过使用分散体系形成均匀的粒子,制造含有平均直径大致小于200nm的锌的混合金属氧化物的催化剂的制造方法。 制造含有金属前体和成型材料的混合溶液。 金属前体由一种或多种材料和锌前体制成。 一种或多种材料选自铬前体,铝前体或钡前体。 通过将沉淀剂注入到混合溶液中来制造共沉淀物。 通过将得到的共沉淀材料进行干燥和塑化来制造化学式1(Zn_a-Cr_b-Al_c-Ba_d-O_e)的含锌混合金属氧化物。 在化学式1中,a为Zn原子的摩尔比,B为Cr原子的摩尔比,C为Al原子的摩尔比,D为Ba原子的摩尔比,E为摩尔比为摩尔 O原子的比例。
