介孔球状钴酸镍纳米材料的制备方法
摘要：
一种介孔球状钴酸镍纳米材料的制备方法，属于电催化技术领域。本发明的目的是利用滴加的方式制备介孔级钴酸镍纳米材料的介孔球状钴酸镍纳米材料的制备方法。本发明分别在含有CoCl26H2O和NH4Cl混合液及Ni(NO3)26H2O的两个容器内投入异丙醇中，用磁力搅拌器搅拌；利用注射泵将丙三醇率分别滴入含有CoCl26H2O和NH4Cl的混合溶液和Ni(NO3)26H2O的溶液中；利用注射泵将两个注射器里的氨水分别滴入含有CoCl26H2O和NH4Cl的混合溶液和Ni(NO3)26H2O的溶液中，并搅拌；将混合溶液倒入以聚四氟乙烯为内衬的特氟龙高压反应釜中，并干燥反应；将干燥后的样品焙烧得到介孔纳米球状钴酸镍材料。本发明能够实现对甲醇的高效电催化氧化，降低催化剂成本，提高对甲醇电催化的稳定性。
摘要（英）：

The invention discloses a preparation method of a mesoporous spherical nickel cobaltate nano material, and belongs to the technical field of electrocatalysis. The invention aims to provide a preparation method of the mesoporous spherical nickel cobaltate nano material in a dropwise adding manner. The preparation method comprises the following steps: respectively putting isopropanol into two containers containing a mixed solution of CoCl2.6H2O and NH4Cl and Ni(NO3)2.6H2O, and stirring by using a magnetic stirrer; respectively dropwise adding glycerol into the mixed solution containing the CoCl2.6H2O and the NH4Cl and a solution containing the Ni(NO3)2.6H2O by using an injection pump; respectively dripping ammonia water in two injectors into the mixed solution containing the CoCl2.6H2O and the NH4Cl and the solution containing the Ni(NO3)2.6H2O by using the injection pump, and stirring; pouring the mixed solution into a Teflon high-pressure reaction kettle taking polytetrafluoroethyleneas a lining, and carrying out drying reaction; and roasting the dried sample to obtain the mesoporous nano spherical nickel cobaltate material. According to the invention, efficient electrocatalytic oxidation of methanol can be realized, the catalyst cost is reduced, and the electrocatalytic stability of methanol is improved.
