  • Inorganic fibrous membrane and a method of fabricating thereof
    Patent number: 10710025
    Abstract: A method of fabricating an inorganic fibrous membrane, the method comprising the steps of: grafting sulfonated graphene oxide onto a scaffold of inorganic nanofibers to form a suspension of heterojunctions of the sulfonated graphene oxide and the scaffold; filtering the suspension through a support to obtain heterojunctions on the support; drying the heterojunctions on the support; and removing the support to obtain the inorganic fibrous membrane.
    Type: Grant
    Filed: April 14, 2014
    Date of Patent: July 14, 2020
    Assignee: NANYANG TECHNOLOGICAL UNIVERSITY
    Inventors: Delai Darren Sun, Jincheng Liu, Tong Zhang
