Catalyst for preparing adipic acid through one-step oxidation of cyclohexane and preparation method of catalyst

The invention discloses a catalyst for preparing adipic acid by one-step oxidation of cyclohexane and a preparation method thereof, and the preparation method comprises the following steps: preparing a bimetal hydroxide by a precipitation method, then carrying out thermal decomposition to obtain a bimetal oxide carrier, and finally preparing a supported catalyst by an impregnation method. Then adding cyclohexane, a solvent and a catalyst into a reaction kettle, adjusting the solution to be alkaline, stirring and heating to a reaction temperature, introducing oxygen to a specified pressure while stirring to react, cooling, discharging and rectifying after the reaction is finished, and analyzing the obtained product by adopting liquid chromatography and gas chromatography to finally obtain the adipic acid. According to the catalyst disclosed by the invention, the cyclohexane is efficiently oxidized into the adipic acid in one step through the oxidation-reduction cycle of the carrier by utilizing the oxidation-r
