CuO nanoclusters coated with mesoporous SiO2 as highly active and stable catalysts for olefin epoxidation†
Abstract
A one-pot solvothermal synthetic method to prepare uniform CuO colloidal nanocrystal clusters (CNCs) with sizes of approximately 60 nm was developed. To enhance their stabilities, the CuO CNCs were coated with mesoporous SiO2 shells to form CuO CNCs@meso-SiO2 nanocomposites. The CuO CNCs as well as the CuO CNCs@meso-SiO2 composite
