  • CARBON-BASED CALCINED MATERIAL AND COMPLEX THEREOF AS WELL AS FUEL CELL USING THE CARBON-BASED CALCINED MATERIAL
    Publication number: 20230238545
    Abstract: A stable form which uses a carbon material having electrical conductivity as a raw material and that the electrical conductivity of the carbon material is retained and/or improved, and which improves the electricity generation properties when used in a catalyst layer for a fuel cell. The present invention is directed to, e.g., a calcined material of a mixture of an aromatic compound having a phenolic hydroxyl group and a carbon material having electrical conductivity.

  • Method for preparing branched alcohol
    Patent number: 10179755
    Abstract: A method for preparing a branched alcohol by dimerizing an aliphatic monoalcohol having three or more carbon atoms in the presence of a base and a catalyst. The dimerization reaction is performed under atmospheric pressure while injecting a hydrogen gas. With this method, it is possible to obtain a dimerized alcohol with excellent yield even when using a branched aliphatic monoalcohol as the starting material.
    Type: Grant
