  • Patent number: 11891303
    Abstract: A catalyst composition for manufacturing a catalyst for hydrogen production based on thermochemical reaction of methanol is disclosed. The catalyst composition includes a support component and an active component. The support component includes cement and clay, wherein a weight ratio of the cement to the clay is 3/7 to 9/1. The active component includes copper oxide or a precursor of copper oxide. Based on 100 parts by weight of the support component, a content of the active component is 5 to 10 parts by weight.
    Type: Grant
    Filed: January 3, 2022
    Date of Patent: February 6, 2024
    Assignee: National Cheng Kung University
    Inventors: Wei-Hsin Chen, Yi-Kai Chih

  • Publication number: 20060163540
    Abstract: A process to manufacture conductive polymer nano material and another process to manufacture all solid status electro-chromic device using the conductive polymer nano material by having soluble ortho-aniline sulfonic acid (meta-aniline sulfonic acid, or 2,5-amiobenzen sulfonic acid) to dissolve in water, added with proper amount of aniline and mixed to be kept at proper temperature for the working temperature to reach equilibrium status; then added into solution of ammonium persulfate (APS) initiator to conduct self-assembly polymerization for availing the conductive polymer nano material, which being further used in the manufacturing of all solid status electro-chromic device.
