英文摘要: Abstract(#br)A new synthetic smectite-like vanadosilicate, named Vanadosilicate Araraquara Madrid (VAM), containing V 3+ was prepared by a hydrothermal method and its behavior as catalyst for methanol oxidation was investigated by X-ray Absorption Spectroscopy (XAS) under operando conditions. The samples were characterized by powder X-ray Diffraction (XRD), Scanning and Transmission Electronic Microscopy (SEM and TEM), CHN chemical analysis, as well as Nuclear Magnetic Resonance spectroscopy, Ultraviolet–visible spectroscopy (UV–Vis) and XAS. The use of VCl 3 as a source of vanadium in low oxidation state (V 3+ ) together with a mixture of hexamethyleneimine (HMI) and N,N,N -trimethyl-1-adamantamonium hydroxide (TMAdaOH) and the preparation of the synthesis mixture under inert atmosphere...
