The SSA and porosity parameters are found to be about 77.1 m 2/g and 0.1–100 nm range, respectively. The EDX results reveal that the elements used for the preparation of samples distribute homogeneously and neither caesium nor carbon atoms enter into the crystal structure indicating the purity of samples. The porous nature of the product has been confirmed by the SEM and evolution of gaseous material from the surface. The average grain size of the synthesized undoped, 0.9 and 1.2 g caesium carbonate-doped samples had 3.61, 10.84 and 12.00 nm, respectively. gBN formation determined by XRD analysis was accelerated and improved ordered lateral polymorph in which graphitization index was found to be very close to the graphite as 2.02 and 1.84 as for 0.9 and 1.2 g dopant level, respectively. The products were characterized by using infrared spectroscopy (FTIR), powder X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), high-resolution transmission electron microscopy (HR-TEM) and specific surface area (SSA) and porosity analysis. The mass ratio of caesium carbonate was adjusted as 0.9 and 1.2 at the constant mass of urea and B 2O 3 in a mixture of 2 g and 1 g, respectively. In this study, the effect of caesium carbonate with a balanced strong base characteristic on the morphology crystallinity, porosity and specific surface area of graphitic boron nitride is reported.
