NOVELTY - Preparation of porous graphene-based antibacterial material involves dispersing titanium dioxide mesoporous beads and silver nitrate in deionized water, dissolving, stirring, adding a precipitating agent, heating resultant mixture at 60-90 degrees C for 5-30 minutes, ultrasonically processing, filtering, vacuum-drying, obtaining mixed crystal mesoporous silver-titanium dioxide antibacterial agent, ultrasonically dispersing graphene oxide in deionized water, obtaining an aqueous solution of graphene oxide, adding a reducing agent, stirring, dissolving, transferring resultant to an autoclave, hydrothermally reacting at 120-200 degrees C for 8-12 hours, cooling to room temperature, obtaining porous graphene solution, mixing with the antibacterial agent, adjusting pH to 9-11 using ammonia, ultrasonically treating for 60-90 minutes, vacuum-drying, washing with ethanol and deionized water, and vacuum-drying. USE - Preparation of porous graphene-based antibacterial material. ADVANTAGE - The method enables preparation of porous graphene-based antibacterial material having suppressed generation of agglomeration.
