BACTERIA/TRANSITION METAL OXIDES ORGANIC-INORGANIC COMPOSITE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A method for manufacturing an organic-inorganic composite comprising bacteria and transition metal oxides is provided to reduce costs and time by simplifying a synthetic process, to enable mass production, and to obtain the organic-inorganic composite having various one-dimensional shapes. CONSTITUTION: A method for manufacturing an organic-inorganic composite comprising bacteria and transition metal oxides comprises the following steps: manufacturing a bacteria dispersion solution by controlling the concentration of the bacteria using deionized water after culturing the bacteria having ion charges; uniformly dispersing bacillus bacteria and a transition metal precursor by adding a transition metal precursor solution to the solution of the previous step and stirring the mixture at 20-30 °C for 0.5-2 hours; making the transition metal oxides attached uniformly to the surface of the bacteria by adding a solution, in which sodium borohydride(NaBH4) is dissolved in the deionized water, to the solution of the previous step and refluxing the mixture; obtaining a precipitate through centrifugal filtration of the refluxed solution; and manufacturing the organic-inorganic composite by drying the precipitate in vacuum state.
