  • Publication number: 20200246779
    Abstract: A catalyst includes a carrier, and a metal obtained by reducing a metal ion supported on the carrier 1) in a supercritical state or 2) in a polar organic solvent, wherein the carrier is an inorganic porous body having a hierarchical porous structure. By employing the catalyst, it is possible to exhibit better catalytic activity than a conventional catalyst. Heat generation and spontaneous ignition are prevented because no organic porous body is used.
