One-pot synthesis of Au-Fe2O3@SiO2 core-shell nanoreactors for CO oxidation
NEW JOURNAL OF CHEMISTRY（2020）
Abstract
Core-shell nanostructured Au-Fe2O3@SiO2 nanoreactors with 3-4 nm Au-Fe2O3 cores and microporous SiO2 shells were prepared by a water-in-oil (W/O) microemulsion method. In comparison with Au@SiO2, the obtained Au-Fe2O3@SiO2 nanoreactors showed a significant improvement in CO oxidation due to the strong interactions between Au and Fe2O3 in the cores.
