Synthesis of a new hybrid nanocomposite based on vanadium (V) substituted Keggin-type polyoxometalate and polyvinyl alcohol ((TBA)₄PMo₁₀V₂@PVA) as a nanocatalyst for germination of barley seeds

Abstract

To investigate a new nanocomposite based on vanadium(V) substituted Keggin-type polyoxometalate as a new nanocatalyst on barley seed germination, nanocomposite (TBA)₄PMo₁₀V₂@PVA was prepared by reaction of H₅PMo₁₀V₂O₄₀, tetrabutylammonium bromide (TBA), and polyvinyl alcohol (PVA) at room temperature via sol-gel method. The synthesized hybrid nanocomposite was characterized by FT-IR, UV-vis, XRD, SEM and ³¹P NMR spectroscopy. The influence of the new organic-inorganic hybrid nanocomposite TBA-PMo₁₀V₂@PVA was investigated in germination of barley seeds. In order to compare, several types of polyoxometalates with different concentrations were used to study their effects on growth factors of barley seeds. The obtained results indicate that using ((TBA)₄PMo₁₀V₂@PVA) with 10 and 100 µM concentrations achieved the most preferred results.
