The invention relates to a preparation method and an application of a chemical copper-plated catalyst for cyclohexene oxidization. The catalyst is a composite material formed by reducing copper by a chemical plating method and depositing the copper on a metal base body. A copper-plated layer mainly comprises 1-50 percent of Cu-Ni alloy; the base body is Co, Al, V, Cr, Mn, Fe, Ni or Zn metal powder, and the mass percentage of the base body is 50-99 percent. The prepared catalyst has the characteristics of low cost, stable activity, no component loss, simplicity in separation, recycling and the like. Under conditions that the temperature is 73-78 DEG C and the oxygen pressure is 10-20atm, the catalyst is used for catalyzing cyclohexene oxidization; the conversion rate of cyclohexene is up to 46.3 percent; the total selectivity of C6 products such as cyclohexene oxide, 2-cyclohexene-1-alcohol, 2-cyclohexene-1-ketone and 2-cyclohexene-1-hydrogen peroxide is up to 90 percent. The catalyst does not need to be treat
