Abstract :

Ionic liquids (IL) with vinyl functionalization as n-dialkyl-3, 3�-bis-1-vinyl imidazolium dibromides ([CnVIm] Br; n=4, 6 and 10) were prepared from vinyl imidazole (VI) and dibromo alkanes such as dibromobutane (DBB), dibromohexane (DBH) and dibromodecane (DBD). Then, polymeric ionic liquid (PIL) microgels as poly(1,4-butanediyl-3,3'-bis-l-vinylimidazolium dibromides) (p(C4VImBr)), poly(1,6-hexanediyl-3,3'-bis-l-vinylimidazolium dibromides) (p(C6VImBr)) and poly(1,10- decanediyl-3,3'-bis-l-vinylimidazolium dibromides) (p(C10VImBr)) microgels were synthesized by photo-initiated inverse suspension polymerization technique using the prepared vinyl functionalized imidazolium monomers. The prepared PIL microgels were characterized with Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and zeta potential. P(C4VImBr), p(C6VImBr) and p(C10VImBr) microgels were used as templates for in situ Co metal nanoparticle synthesis, and the prepared composite PIL microgels: p(C4VImBr)-Co, p(C6VImBr)-Co and p(C10VImBr)-Co were used as catalyst in (H2) generation from the hydrolysis reaction of NaBH4. H2 generation rate was evaluated by changing various parameters such as the types of PIL microgels as template, the amounts of Co metal nanoparticles as catalyst, the number of re-use of composite PIL catalyst and the reaction temperature.
