Abstract:A highly dispersed carbonate‐intercalated Cu2+‐Al3+ layered double hydroxide (CuAl LDH) was created on an unreactive α‐Al2O3 surface (CuAl LDH@α‐Al2O3) via a simple coprecipitation method of Cu2+ and Al3+ under alkaline conditions in the presence of α‐Al2O3. A highly reducible CuO nanoparticles was generated, accompanied by the formation of CuAl2O4 on the surface of α‐Al2O3 (CuAlO@α‐Al2O3) after calcination at 1073 K in air, as confirmed by powder X‐ray diffraction (XRD) and Cu K‐edge X‐ray absorption near edg… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
