Electrochemical Evaluation of Catalytic Activity of Various Types of LDH/Mo10V2-Pd: Application of FeNi/Mo10V2-Pd as an Efficient and Reusable Nano Catalyst in the Heck Coupling Reactions.

Palladium nano particles deposited on various forms of layered double hydroxide intercalated 10-molybdovanado phosphate (M(III)M(II)/Mo 10 V 2 -Pd) were synthesized. Their electrocatalytic behavior and collaboration of all components of synthesized catalysts were evaluated in Heck coupling reaction. According to the obtained results from electrochemical and catalytic investigations, FeNi/Mo 10 V 2 -Pd was chosen as the best in term of productivity. The structural features of FeNi/Mo 10 V 2 -Pd were characterized by SEM, EDX, TEM, FT-IR, XRD, ICP-AES, LSV, chronoamperometry and CV analyses. The presence of Mo 10 V 2 improved the catalytic activity of FeNi-Pd in the Heck coupling reaction. Also collaboration of Pd and Mo 10 V 2 with FeNi LDH as a support was studied. This reusable solid catalyst exhibited excellent activity and the methodology is applicable to diverse substrates providing good to excellent yields of desired products. This method has advantages of high yields, low reaction times, elimination of ligand and base, heterogeneous reusable catalysts and simple methodology. [ABSTRACT FROM AUTHOR]
