Summary:The amine functionalized cubic mesoporous silica nanoparticles (cSiO 2 -NH 2 ) were successfully synthesized through biphasic stratification approach. The synthesized material was characterised by various spectroscopic and physicochemical techniques; such as, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscope, transmission electron microscope and Brunauer–Emmett–Teller surface area. The mesoporous cubic silica nanomaterial (SiO 2 -NH 2 ) was utilized as recyclable catalyst for liquid phase Knoevenagel condensation reaction. The catalyst could be easily recovered by simple methods like, filtration and centrifugation and be reused for multiple catalytic cycles without any noticeable effect on its activity.
