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. The mass ratio of caesium carbonate was adjusted as 0.9 and 1.2 at the constant mass of urea and B₂O₃ in a mixture of 2 g and 1 g, 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. 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 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. The porous nature of the product has been confirmed by the SEM and evolution of gaseous material from the surface. 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 SSA and porosity parameters are found to be about 77.1 m²/g and 0.1–100 nm range, respectively. Caesium carbonate propagated the graphitic nature and crystallinity of BN at a lower temperature than O’Connor method due to rise in electronic interaction as a basic compound.

在这项研究中，据报道具有平衡的强碱特性的碳酸铯对石墨氮化硼的形态结晶度，孔隙率和比表面积的影响。在尿素和B ₂ O _3的质量恒定的情况下，碳酸铯的质量比被调节为0.9和1.2。分别为2克和1克的混合物。使用红外光谱（FTIR），粉末X射线衍射分析（XRD），扫描电子显微镜（SEM），能量色散X射线光谱（EDS），高分辨率透射电子显微镜（HR-TEM）对产品进行表征）和比表面积（SSA）和孔隙率分析。通过XRD分析确定的gBN形成得到加速，并改善了有序的横向多晶型物，其中石墨化指数非常接近石墨（分别为0.9和1.2 g的掺杂剂，分别为2.02和1.84）。合成的未掺杂，0.9和1.2 g碳酸铯掺杂样品的平均晶粒尺寸分别为3.61、10.84和12.00 nm。产物的多孔性已经通过SEM和从表面释放出气态物质的证实。EDX结果表明，用于制备样品的元素分布均匀，铯和碳原子均未进入晶体结构，这表明样品的纯度。发现SSA和孔隙率参数约为77.1 m² / g和0.1–100 nm范围。由于作为基本化合物的电子相互作用的增加，碳酸铯在比O'Connor方法更低的温度下传播了BN的石墨性质和结晶性。
