文摘

•: Spinel ZnCo₂O₄ nanosheets were fabricated by a facile template-free wet chemical method.
•: ZnCo₂O₄ nanosheet supported Au catalyst exhibited a good stability for oxidizing CO.
•: Visible light could promote the adsorption and activation of CO and O₂ on Au/ZnCo₂O₄.
•: A efficient charge transfer occurred on the interface of Au and ZnCo₂O₄.
