Abstract

Hydrotalcite-supported gold nanoparticles (Au/HT) were synthesized by depositionprecipitation using NH3 and successive calcination at various temperatures. Gold nanoparticles of less than 5 nm with narrow size distribution were deposited onto hydrotalcite surfaces, which were determined by TEM measurements. Au LIII-edge XANES spectra clearly indicated that calcination at temperatures higher than 373K leads to the generation of metallic Au which is the catalytically active site for selective glycerol oxidation to glycolic acid in water with molecular oxygen under mild reaction conditions.
