Abstract

Abstract : Pt-CoO x @HMANs show excellent catalytic activity, selectivity and stability in the hydrogenation of substituted nitroaromatics due to the improved mass transfer, the strong interaction between Pt and CoO x domains, and the introduction of Al2 O3 . Abstract : Hollow and mesoporous aluminosilica nanoreactors (HMANs) with Pt-CoO x cores (∼4.7 nm) and hollow aluminosilica shells (∼50 nm) were designed by a selective etching method. The Pt-CoO x @HMANs demonstrate a greatly enhanced activity and selectivity for the hydrogenation of various substituted nitroaromatics compared to Pt@HMANs and Pt-CoO x @SiO2 .
