A general one-pot strategy for the synthesis of Au@multi-oxide yolk@shell nanospheres with enhanced catalytic performance.

ABSTRACT: By integrating redox self-assembly and redox etching processes, we report a general one-pot strategy for the synthesis of Au@multi-M _x O _y (M = Co, Ce, Fe, and Sn) yolk@shell nanospheres. Without any additional protecting molecule or reductant, the whole reaction is a clean redox process that happens among the inorganic metal salts in an alkaline aqueous solution. By using this method, Au@Co₃O₄/CeO₂ (Au@Co-Ce), Au@Co₃O₄/Fe₂O₃ (Au@Co-Fe), and Au@CeO₂/SnO₂ (Au@Ce-Sn) yolk@shell nanospheres with binary oxides as shells, Au@Co₃O₄/CeO₂/Fe₂O₃ (Au@Co-Ce-Fe) yolk@shell nanospheres with ternary oxides as shells
