Abstract (en)
[origin: EP3680368A1] A method for preparing a hollow fiber composite is disclosed. The method for preparing a hollow fiber composite comprises the steps of: preparing a polymer fiber; providing, on the polymer fiber, a precursor containing nitrogen; and heat treating the polymer fiber having the provided precursor, wherein the precursor is heat treated to be converted into a catalyst and the polymer fiber is heat treated to have cavities formed therein.
