	                	Well-defined gold nanoclusters with average size less than 2 nm have emerged as a new and novel catalyst. The gold nanocluster loaded on the oxide surface usually aggregates to larger particles at high temperature (>300℃), which is caused by the removal of the surface ligands. We herein present a novel method to prepare Au25 cluster catalyst (~1.3 nm) with high thermal stability (up to 400℃). Au25@SiO2 is synthesized via a co-hydrolyzing reaction of Au25[SC3H6Si(OCH3)3]18 and tetraethyl orthosilicate, and then it is treated at different temperature (e.g., 200, 300, 400℃) in air to remove the organic ligands. Au25@SiO2 is well characterized by transmission electron microscopy, ultraviolet-visible spectroscopy and diffuse reflectance UV-vis spectroscopy. Further, the Au25@SiO2 catalysts are investigated in the hydrogenation of p-nitrophenol into p-aminophenol.
