Abstract

Nano-gold (sub-5 nm)@mesoporous-silica (m-SiO2) core–shell nanospheres with controlled size and core number were prepared via a soft-templated method. The single-core Au@m-SiO2 particles showed great sintering-resistance at 750 °C and kept high catalytic activity for CO oxidation after the treatment.
