| Popis: | The divanadium-substituted molybdophosphate acid, H 5 PMo 10 V 2 O 40 ·13H 2 O was synthesized by acidification-etherate. It was proved that the obtained compound has the Keggin structure. A Langmuir–Blodgett (LB) film with the PMo 10 V 2 O 40 5− heteropolyanion in the subphase was formed. Remarkable modifications of the compression isotherms indicate that the heteropolyanion interacts with the octadecylamine hydrochloride (ODA) monolayer. Atomic force microscopy (AFM), low-angle X-ray diffraction (LAXD), FT-IR and UV spectroscopy were used to investigate the morphology and molecular structure of the deposited ODA/PMo 10 V 2 O 40 5− LB film. The cyclic voltammetric (CV) behavior of the PMo 10 V 2 O 40 5− heteropolyanion and the LB films of ODA/PMo 10 V 2 O 40 5− deposited onto a glassy carbon electrode were studied. |
