| description | The invention belongs to the field of catalysts, particularly relates to the technical field of catalyst preparation, and relates to a preparation method and application of a catalyst. The preparation method of the catalyst comprises the following steps: 1) weighing cerous nitrate hexahydrate solid powder, dissolving the cerous nitrate hexahydrate solid powder in water, and carrying out ultrasonic treatment to prepare a solution A; and weighing sodium hydroxide solid powder, dissolving the sodium hydroxide solid powder in water, carrying out ultrasonic treatment to prepare a solution B, dropwise adding the solution B into the solution A, carrying out stirring reaction in a constant-temperature state until milk white precipitate is generated, and carrying out hydrothermal synthesis to obtain cerium oxide; 2) centrifuging, washing, drying, grinding and calcining the cerium oxide obtained in the step 1) to obtain cerium oxide powder; and 3) impregnating the cerium oxide powder prepared in the step 2) in a nickel |
