  • Patent number: 11850572
    Abstract: Disclosed herein are an activated carbon catalyst for hydrogen peroxide decomposition, a preparation method thereof and a hydrogen peroxide decomposition method using the same. The activated carbon catalyst for hydrogen peroxide decomposition, provided in an aspect of the present invention may be easily prepared through the carbonization and activation of an ion exchange resin, and safer and higher decomposition efficiency of hydrogen peroxide may be achieved than the conventional catalyst for hydrogen peroxide decomposition through the control of the manganese content and pore properties in the catalyst.
    Type: Grant

  • Publication number: 20230312352
    Abstract: The present invention provides a hyper-branched polymer having a three-dimensional structure, which is applicable to treatment of harmful substances in the atmosphere and has antibacterial activity, as well as a method for manufacturing the same. Further, the present invention provides an antibacterial spherical activated carbon which is ultimately obtained using the hyper-branched polymer as a precursor. The antibacterial spherical activated carbon, which is the final product according to the present invention, may induce a chemical bonding of ion bonds in an antibacterial component to a carrier without use of a separate binder, thereby stably immobilizing the antibacterial component. Furthermore, it is possible to adjust a loading amount of the antibacterial component as well as a specific surface area of the carrier through a simple operation.
