Trapped inside: A new catalyst was developed where gold nanoparticles are encased inside hollow titania nanospheres (see picture). The new nanoarchitecture prevents the nanoparticles from sintering and losing their activity while still providing the reactants free access to the metal surface. The result is a catalyst capable of promoting the oxidation of CO at room temperature while surviving calcination at temperatures above 775 K.
