Easy in, easy out: Mass transport through TiO2 and SiO2 shells was probed in the liquid phase with IR spectroscopy by detecting carbon monoxide adsorption in Pt@void@TiO2 yolk–shell and Pt@SiO2 core–shell nanostructures (see picture; C green, O red, Pt pale red). Adsorption was observed on the surface of Pt nanoparticle cores, and on the inner face of the TiO2 shells in the yolk–shell case.
