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.
