|1. (WO2017154927) GOLD COMPOSITE MATERIAL, METHOD FOR MANUFACTURING SAME, AND GOLD NANOCATALYST|
|Applicants:||TOKYO METROPOLITAN UNIVERSITY
|Title:||GOLD COMPOSITE MATERIAL, METHOD FOR MANUFACTURING SAME, AND GOLD NANOCATALYST|
[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.
