摘要：

Core-shell SiO2@Au@TiO2 materials have shown excellent catalytic performances in the base-free oxidation of furfural (FF) to furoic acid (FA). The enhanced catalytic behaviour with respect to that observed over supported SiO2@TiO2@Au catalysts suggests a key role of the TiO2 shell, which could prevent Au deactivation by irreversible FA adsorption, improve metal-oxide interaction and presumably, give rise to the formation of new active sites located at the perimeter of the Au-TiO2 interface.
