Abstract

Solvothermal synthesis of Cu2O cubes from Cu(OAc)2 in ethanol provided templates for tunable formation of novel multicomponent composites: hollow CeO2-Cu2O (), core-shell NiO@Cu2O () and hollow CeO2-NiO-Cu2O (). Composites catalyze the oxidation of CO at a lower temperature than the parent Cu2O cubes.
