The present invention belongs to the field of medical materials. A nano-oxide/kaolin composite hemostatic antibacterial material includes an iron oxide/kaolin composite carrier, and zinc oxide supported on the surface of the composite carrier. The present invention further provides the preparation and application of the composite hemostatic antibacterial material. Furthermore, the present invention provides a hemostatic healing-promoting dressing including the composite hemostatic antibacterial material disclosed by the present invention. The present invention surprisingly finds from research that the zinc oxide and iron oxide/kaolin composite carrier have a synergistic effect, and further cooperated with a special loading morphology, the synergistic effect of the two is unexpectedly enhanced, the hemostatic property and antibacterial property of the material are effectively improved, and moreover, the rate of wound healing is further improved.
