A naturally benign convention was created with a surface change of graphene oxide by citrus extract as catalyst was prepared by astraight-forward chemical modification method. The prepared catalyst′s catalytic activity was examined by the synthesis of imidazolederivatives at room temperature. It shows a strong acidic catalytic and sustainable organocatalyst. The prepared catalyst was characterizedusing different analytical procedures like elemental analysis, Fourier transforms infrared spectroscopy (FT-IR), powder X-ray diffraction(PXRD), energy-dispersive X-ray analysis (EDS), scanning electron microscopy images (SEM) and transmission electron microscopyimages (TEM) analysis. The catalytic activity shows high activity and can be reused without significant loss of catalytic activity after fivetimes. A present catalyst works easily under room temperature.
