dc.description.abstractThe immobilization of gold nanoparticles (Au NPs) on silica is made possible by the functionalization of the silica surfaces with organosilanes. Au NPs could only be stabilized and firmly attached to silica‐support surfaces that were previously modified with amino groups. Au NPs could not be stabilized on bare silica surfaces and most of the NPs were then found in the solution. The metal–support interactions before and after the Au NP formation, observed by X‐ray absorption fine structure spectroscopy (XAFS), indicate a stronger interaction of gold(III) ions with amino‐modified silica surfaces than with the silanol groups in bare silica. An amino‐modified, silica‐based, magnetic support was used to prepare an active Au NP catalyst for the chemoselective oxidation of alcohols, a reaction of great interest for the fine chemical industry.pt_BR
