The invention relates to a parachloronitrobenzene hydrogenation reduction catalyst capable of being magnetically recycled and a preparation method. Prepared Fe3O4 nanometer magnetic particles and water-soluble cobalt salt are added into water; ultrasonic full mixing is performed under the protection of inert gas, a reducing agent is added, and a target product is obtained after full reaction under ultrasound. Relevant salts such as iron and cobalt which are rich in nature are adopted as a matrix, raw materials are easy to obtain, and the cost is low. The prepared catalyst can be recycled through an external magnetic field due to the fact that the catalyst contains the Fe3O4 nanometer magnetic particles. The grain size of the prepared catalyst is 5-30 nm, so that the specific surface area can be 100-180 m<2>/g, and thus extremely huge promoting effects can be achieved on reagent adsorption and dispersion in the catalytic reaction process, and finally the conversion rate and selectivity reach 100%. The preparation method is simple, low in energy consumption, environmentally friendly and suitable for industrial production.
