This paper describes a trans-deposition method for the size-controlled preparation of metal oxide-supported gold nanoclusters (AuNCs) varying from 1 to 8 nm in diameter. Colloidal AuNCs of various sizes were successfully deposited on hydroxyapatite (HAP), without undergoing a significant change in size from the initial polymer-supported AuNCs. The resulting AuNCs deposited on HAP (Au:HAP) were characterized by transmission electron microscope, powder X-ray diffraction, X-ray photoelectron spectroscope, inductively coupled plasma atomic emission spectroscopy, and X-ray absorption spectroscopy. The Au:HAP thus obtained catalyzed the aerobic oxidation of 1-indanol to give 1-indanone with excellent yield and recyclability.Mahidol UniversityChemical EngineeringChemistryEngineeringArticleSCOPUS10.1166/jnn.2017.13777
