Catalyst precursor, catalyst material, and catalyst production method |
| abstract |
Provided is a novel catalyst material obtained by fixing a metal species to a specific solid acid and removing nitrogen oxides in exhaust gas. The catalyst precursor of the present invention comprises amorphous carbon into which a metal salt of an acidic group is introduced. The catalyst precursor is synthesized by mixing amorphous carbon into which an acidic group has been introduced and an aqueous solution containing metal ions and performing ion exchange. By reducing this catalyst precursor, the catalyst material of the present invention is obtained. The catalyst material is composed of a microcarrier made of graphene sheet possessed by amorphous carbon, and a catalytic metal supported on the microcarrier after reduction of metal ions. The catalyst material is supported on a microcarrier (graphene sheet) and the metal ions fixed to the carbon solid acid have a bond with the microcarrier, so that the catalyst metal grain growth is suppressed and excellent NOx reduction activity even at low temperatures. Indicates. [Selection] Figure 7 |
