GOLD ULTRA-FINE PARTICLE CARRIER, MANUFACTURE METHOD THEREFOR AND CATALYST COMPRISING THE CARRIER

摘要

PROBLEM TO BE SOLVED: To obtain a novel gold ultra-fine particle carrier with a high activity and an excellent selectivity useful in a catalyst for various kinds of reactions in which the carrier having a small specific surface area and a low activity is carried with a large amount of gold ultra-fine particles.

SOLUTION: In the gold ultra-fine particle carrier, an inorganic oxide having a specific surface area of 30 m2/g or less according to BET method is used as the carrier and the carrier is carried with 3 pts.wt. or more of gold ultra-fine particles having an average particle diameter of 25 mm or less based on 100 pts.wt. of the inorganic oxides.
