発明の名称 (英語) GOLD COMPOSITE MATERIAL, METHOD FOR MANUFACTURING SAME, AND GOLD NANOCATALYST
発明の概要(英語) [Problem] To provide a novel gold composite material having higher catalytic activity than conventional gold nanoparticle catalysts, a method for manufacturing the gold composite material, and a gold nanocatalyst in which the gold composite material is used.
[Solution] A gold composite material comprising a carrier and gold microparticles carried on the carrier, the gold composite material being characterized in that the carrier is an acidic solid metal oxide. A method for manufacturing a gold composite material, wherein the method for manufacturing a gold composite material is characterized in being provided with a carrying step for carrying gold microparticles using the acidic solid metal oxide and a gold colloid solution, and in the carrying step, a solid metal oxide having a high specific surface area of at least 20 m2/g is used as the solid metal oxide, and a gold colloid solution containing gold particles having a particle diameter of 5 nm or less is used as the gold colloid solution.
従来技術、競合技術の概要(英語) BACKGROUND ART
Gold nanoparticles supported on the support as is known to show high catalytic ability and, various gold nanoparticle catalyst have been proposed.
Patent Document 1 is for example, of gold nanoparticles as the support for the non-noble metal oxide, noble metal oxide is MoO3 CuO and one or more selected from the group consisting of whether the 1, 1 or composite oxide containing two or more them by selecting, in the gaseous phase and acetaldehyde from ethanol can be selectively produced, gold nano-catalyst has been proposed.
In addition, Patent Document 2 is, as a catalyst used in the preparation of the pyridine compound, the surface of the carrier surface immobilized gold nanoparticles immobilized gold and use of a catalyst, the surface immobilized gold as a catalyst, hydroxyapatite (HAP), titania (TiO2) 、alumina (Al2 O3) 、magnesia (MgO), silica (SiO2) 、ceria (CeO2) 、such as activated carbon is used as a carrier (C) is disclosed.
