Abstract
A series of ionic solid nanomaterials denoted as IS1, IS2 and IS3 have been prepared using butylmethylimidazolium bromide ([BMIM][Br]) ionic liquid as cation, and three types of heteropolyacid; phosphotungstic acid (H3PW12O40), phosphomolybdic acid (H3PMo12O40), and silicotungstic acid (H4SiW12O40) as anion. The nanomaterials were characterized by FTIR, XRD, SEM, TGA, NH3-TPD and BET. Its catalytic performance was investigated by catalyzing glucose conversion to levulinic acid and hydroxymethylfurfural. It was observed that the ionic solids have higher acidity with semi amorphous structure, higher thermal stability and insignificant water content compared to the parent compound. Among the three prepared ionic solids, phosphomolybdic based ionic solid (IS2) exhibited the best catalytic performance due to its highest total acidity.
