The invention discloses a preparation method of a
copper-based MOFs loaded nano-
copper antibacterial material and application of the
copper-based MOFs loaded nano-copper antibacterial material in tobacco charging essence, and the preparation method comprises the following steps: ultrasonically dispersing 1, 3, 5-benzenetricarboxylic acid in
dimethylformamide to form a solution A; adding CuSO4. 5H2O into deionized water, and dissolving to form a solution B; mixing the solution A and the solution B, centrifugally filtering, and
drying to obtain a
ketone-based MOFs
composite material; the preparation method comprises the following steps: adding CuSO4. 5H2O into deionized water, dissolving, and adding a copper-based MOFs material; the preparation method comprises the following steps: dissolving
potassium borohydride,
potassium hydroxide and hexadecyl trimethyl
ammonium bromide in deionized water to prepare a
reducing agent / protective agent
mixed solution; after the
copper sulfate solution is heated to 40-60 DEG C, a
reducing agent / protective agent
mixed solution is dropwise added, and when the solution becomes
brick red, the PH is adjusted to 1-2 with dilute
sulfuric acid; and pouring a
sodium hypophosphite solution, stirring, centrifuging, and
drying to obtain the copper-based MOFs loaded nano-copper material. The copper-based MOFs loaded nano-copper antibacterial material provided by the invention can be used for carrying out rapid cold sterilization treatment on the flavoring essence, so that the
shelf life of the flavoring essence is prolonged, and
mildew and deterioration are prevented.
