Facile, General and Template-Free Construction of Monodisperse Yolk-Shell Metal@Carbon Nanospheres

Abstract

Yolk-shell nanostructures, representing multiple-discrete functional components incorporated in one unit, have been one of the most fertile arenas in materials chemistry. However, the commonly used multi-step synthetic templating approach involving selective etching of interlayers is essentially harsh and tedious. Thus it remains a challenge to explore versatile strategies without sacrificial templates to develop well-defined yolk-shell nanostructures. Here we report a template-free protocol to construct novel yolk-shell Au@carbon nanospheres (YS-Au@CNs) based on the confined interfacial copolymerization. Our proposed strategy greatly simplifies synthetic routes, yields uniform nanospheres with controllable diameters, achieves highly porous carbon shells, and can be generalized to other metal yolk nanoparticles. The YS-Au@CNs showed improved adsorption capacity towards ethanethiol as well as high catalytic ability, owing to the synergistic effect of functional Au core and highly porous carbon shell.
