Acid catalysts facilitate many chemical reactions. Sulfonated reduced grapheneoxide (rGOPhSO 3 H) has shown to be an encouraging solid acid catalyst because of its efficiency, cost-effectiveness and safety of use. In this study, we prepared the rGOPhSO 3 H nano acid catalyst, with the introduction of aromatic sulfonic acid radicals onto GO by fractional removal of oxygenated functions. It was thoroughly characterized by FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, energy dispersive spectroscopy (EDS) and solid state  13 C MAS NMR (SSNMR). Here we report the conversion of CO 2  (1.0 atm pressure, at = 50 °C, the source of C 1  carbon feed stock) with hydrazides and a catalytic amount rGOPhSO 3 H, which through a cyclization reaction results in a new strategy for the synthesis of 5-substituted-3H-[1,3,4]-oxadiazol-2-ones (SOxdOs) under ultrasonic irradiation. Hence this concept of cyclization opens up for new insights
