The invention discloses a biological auxiliary synthesis method of a photocatalyst with antibacterial performance, which comprises the following specific steps: adding the multi-walled carbon nano-tube into the mixed acid of concentrated sulfuric acid and concentrated nitric acid, and stirring at room temperature. Preparing the acidified carbon tube and ferric trichloride hexahydrate solid into aqueous solution according to a certain mass ratio, adding urea and sodium alginate, transferring the aqueous solution into a reaction kettle for heating, cooling to room temperature after the reaction is finished, centrifuging, cleaning and drying the obtained product to obtain MWCNTs/Fe 3 O 4 . Obtained MWCNTs/Fe by utilizing silane coupling agent APTES 3 O 4 And (4) carrying out modification. Modified MWCNTs/Fe 3 O 4 And AgNO 3 Preparing aqueous solution according to a certain mass ratio, adding urea and sodium alginate, transferring into a reaction kettle, heating in an oven, and magnetically separatingThe resulting product is isolated, washed and dried. The obtained MWCNTs/Fe 3 O 4 The Ag has good antibacterial performance and excellent catalytic performance in antibacterial experiments. |
