High‐Temperature‐Stable Catalysts by Hollow Sphere Encapsulation

Abstract

Stable companions: Hollow zirconia shells that each contain one gold nanoparticle (see picture) are stable to sintering and can be used as heterogeneous catalysts in reactions such as the oxidation of CO in air. The performance of Au, @ZrO2 is unaffected by calcination at 800 °C.
