| 英文摘要 | 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 degrees C), which is caused by the removal of the surface ligands. We herein present a novel method to prepare Au-25 cluster catalyst (similar to 1.3 nm) with high thermal stability (up to 400 degrees C). Au-25@SiO2 is synthesized via a co-hydrolyzing reaction of Au-25[SC3H6Si(OCH3)(3)](18) and tetraethyl orthosilicate, and then it is treated at different temperature (e.g., 200, 300, 400 degrees C) in air to remove the organic ligands. Au-25@SiO2 is well characterized by transmission electron microscopy, ultraviolet-visible spectroscopy and diffuse reflectance UV-vis spectroscopy. Further, the Au-25@SiO2 catalysts are investigated in the hydrogenation of p-nitrophenol into p-aminophenol. (C) 2016, Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
