The invention discloses a Co (II)&Zn(II)&Cu (II) doped hydrotalcite, preparation method and application thereof, and Co (II)&Zn(II)&The preparation method of the Cu (II) doped hydrotalcite comprises the following steps: mixing hydrotalcite, Co (II) salt, Zn (II) salt and Cu (II) salt, ball-milling in a ball-milling tank at room temperature, and placing the ball-milled granular powder product in a N 2 High-temperature treatment under atmosphere, cooling, stirring and washing the product for 1.0-10.0 h by using 0.5-10.0 mol/L hydrochloric acid aqueous solution, filtering, washing until the pH value is 3.0-8.0, and vacuum drying to obtain Co (II)&Zn(II)&Cu (II) doped hydrotalcite. Co (II) of the present invention&Zn(II)&The Cu (II) doped hydrotalcite has simple preparation and low cost and is easy for industrial application. Prepared Co (II)&Zn(II)&The Cu (II) -doped hydrotalcite has a good application effect in the catalytic oxidation reaction of cycloalkane, and the application method has the advantages of high selectivity of cycloalkyl alcohol and cycloalkyl ketone, low reaction temperature, few byproducts, small environmental influence and the like, and has the advantages of low content of cycloalkyl peroxide, high safety coefficient and the like. |
