  • Method for manufacturing photocatalytic filter for air purification
    Patent number: 11576995
    Abstract: Disclosed is a method for manufacturing a photocatalytic filter for air purification. The present manufacturing method comprises the steps of: oxidizing a titanium metal to obtain a nanostructured titanium dioxide (TiO2); adding the nanostructured titanium dioxide to an acidic fluorine-containing solution to allow a reaction to occur therebetween for a predetermined period of time; and, after treatment in the acidic fluorine-containing solution, performing heat treatment on the nanostructured titanium dioxide.
    Type: Grant
    Filed: July 31, 2018
    Date of Patent: February 14, 2023
    Inventors: Jee-yeon Kim, Wonyong Choi, Seunghyun Weon, Sae-mi Kim, Hee-jin Park
  • Method for producing photocatalyst and photocatalyst filter for air cleaning
    Patent number: 11452994
    Abstract: Disclosed is a method for producing a photocatalyst for air cleaning. The present production method comprises the steps of: preparing titanium dioxide (TiO2); attaching platinum to a surface of the titanium dioxide; and attaching fluoro to the platinum-attached surface of the titanium dioxide to obtain surface-modified titanium dioxide.
