Abstract

SULFATED TITANIA nanoparticles (SO4 2-/TiO2 NPs) were synthesized using titanium tetraisopropoxide (TTIP) by the SOL-GEL method.The structure and morphology of the prepared NANOCATALYST was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET) methods as well as Fourier transform infrared (FT-IR) and energy dispersive X-ray (EDX) spectroscopy. The obtained nanoparticles were used as an efficient, reusable and environmentally friendly catalyst for the synthesis of POLYHYDROQUINOLINE (PHQ) derivativesvia a one-pot multicomponent reaction of various aldehydes, ammonium acetate and 1, 3-dicarbonyl compounds under reflux conditions.The desired HANTZSCH esters were obtained in good to excellent yields and short reaction times. The SO42-/TiO2 NPs could be recycled at least three times without significant loss of their catalytic activity.
