7969 759 AuNP–CeO2 NP@GO SEM From the SEM images, we observed a combination of clumped particles of AuNP–CeO2 NPs spread across the surface of crumpled flaky sheets of stacked, folded and wrinkled GO. The observed morphological feature provides a strong affirmation that AuNP–CeO2 NPs were effectively anchored onto GO nanosheets
