CERAMIC NANOFIBER STRUCTURE, CERAMIC NANOFIBER SEPARATION MEMBRANE MODIFIED WITH PHOTOCATALYST, AND METHOD FOR MANUFACTURING SAME

摘要

Provided are: a ceramic nanofiber structure having excellent flexibility; a ceramic nanofiber membrane having excellent photocatalytic efficiency; and production methods therefor. The ceramic nanofiber structure according to one embodiment of the present disclosure includes a first ceramic component and a second ceramic component. It is possible to obtain a ceramic nanofiber structure having excellent flexibility by controlling the mean diameter of ceramic nanofibers to control the mean pore size and largest pore size between the nanofibers and adding a second ceramic component to reduce the grain size. The ceramic nanofiber membrane according to one embodiment of the present disclosure includes the ceramic nanofiber structure and an inorganic photocatalyst coating layer. It is possible to obtain a membrane which has excellent photodegradation ability for organic matters and may retain photocatalytic efficiency for a long period of time by including the ceramic nanofiber structure having excellent flexibility and the inorganic photocatalyst coating layer formed on the surface of the nanofiber.
