The invention discloses a preparation method of an insoluble magnetic graphene/cobalt composite catalyst and application of the insoluble magnetic graphene/cobalt composite catalyst to catalyzing Oxone to degrade dyestuff wastewater and belongs to the technical field of synthesis of a composite photocatalytic material and degradation of the dyestuff wastewater. The technical scheme disclosed by the invention is characterized in that the preparation method of the insoluble magnetic graphene/cobalt composite catalyst comprises the following steps: synthesizing a magnetic cobalt catalyst, synthesizing graphene oxide and synthesizing a target product insoluble magnetic graphene/cobalt composite catalyst. The prepared insoluble magnetic graphene/cobalt composite catalyst can be used for effectively catalyzing the Oxone to degrade the dyestuff wastewater. The insoluble magnetic graphene/cobalt composite catalyst prepared by the preparation method has relatively good insolubility in neutral and alkaline environments
