The invention discloses a rapid preparation method and application of a porous hollow tubular CoS2/NiS2 heterojunction, and belongs to the technical field of heterojunction catalyst material preparation. The porous hollow tubular CoS2/NiS2 heterojunction is prepared by utilizing a hydrogen bond organic framework as a support body and utilizing a Joule heat high-temperature impact technology under the action of cobalt salt, nickel salt and thioacetamide. The HER overpotential of the porous hollow tubular CoS2/NiS2 heterojunction in 10mA. Cm <-2 > 1M KOH electrolyte is less than or equal to 85.46 mv, is superior to that of a heterojunction material prepared by a traditional preparation method, is close to the level of a commercial 20wt% Pt/C noble metal catalyst, and has a good industrial application prospect. The synthesis method disclosed by the invention is simple, efficient and low in cost, and industrial large-scale preparation is easy to realize. 本发明公开了一种多孔中空管状CoS2/NiS2异质结的快速制备方法及其应用，属于异质结催化剂材料制备技术领域。本发明利
