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.
