From the organized nanoparticles of copper and vanadium containing LDHs to the small nanoparticles of mixtures of mixed oxides: A simple route

Abstract

Well-dispersed nanoparticles of homogeneous mixtures of mixed oxides with an average size of 2.7 nm are obtained by using as precursors copper and vanadium containing layered double hydroxides (LDHs) possessing new self-organized morphology characteristics. The tailored organized pattern of the large nanoparticles of LDHs and the formation of the small nanoparticles of the mixed oxides are followed by the TEM analysis; the evolution from the clay structure to the mixtures of copper and vanadium mixed oxides is confirmed by the XRD analysis.
