In this work, graphene oxide (GO) nanoparticles were synthesized and subsequently modified using 3-aminopropyltrimethoxysilane (APTMS). An Anderson-type polyoxometalate [(C4H9)4N]2[CrMo6O18(OH)6] was then immobilized on the surface of nanoparticles. The obtained catalyst characterized Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray (EDS), inductively coupled plasma (ICP), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Raman spectroscopy, diffraction (XRD). catalytic performance recyclable hybrid evaluated for synthesis benzimidazole derivatives at 75 °C under solvent-based conditions. demonstrated easy separation could be successfully reused least six times with only a slight reduction in yield desired product. Leaching recovery tests, along FT-IR analysis, confirmed high stability catalytically active species heterogeneous nature catalyst.
