Abstract Graphitic Carbon Nitride (g-C3N4) have been synthesized through melamine by using hydrothermal method. In this paper work degradation organic dyes used such as MB, MO and Rh-B are used for water purification. Remarkably, it has been studied that the synthesis of (g-C3N4) along with factors of dye loading and temperature variation manipulating the photo-degradation process. We have prepared the g-C3N4 by hydrothermal method using a wide ranging of characterization techniques such as SEM, EDX, TEM, XRD, FTIR, UV, XPS and CV. The SEM morphology of g-C3N4 like nano spheres shapes are observed. EDX analysis are observed two peaks nitrogen and carbon. UV–visible analysis for the band gap calculated value is 2.74 eV. XRD observed the peak 27.9° that the hexagonal phase structure with the miller indices (0 0 2). FTIR analysis the functional groups. CV studied for the specific capacitance. Furthermore, we have studied the efficiencies in these organic dyes MO 97.3%, MB 91.1% and Rh-B 99.6%. These efficiencies was obtained vary the dye loading. Hence, g-C3N4 can be well-thought-out as a potential candidate these pollutants as MO, MB and Rh-B for the water purification.

温度变化和染料负载g-C3N4对有机染料的降解作用

摘要 以三聚氰胺为原料，采用水热法合成了石墨氮化碳(g-C3N4)。在本文中，降解有机染料如 MB、MO 和 Rh-B 用于水净化。值得注意的是，已经研究了（g-C3N4）的合成以及染料负载和温度变化操纵光降解过程的因素。我们已经通过水热法制备了 g-C3N4，使用了广泛的表征技术，例如 SEM、EDX、TEM、XRD、FTIR、UV、XPS 和 CV。观察到类似纳米球形状的 g-C3N4 的 SEM 形貌。EDX分析观察到两个峰氮和碳。带隙计算值的紫外-可见分析为 2.74 eV。XRD观察到具有密勒指数(0 0 2)的六方相结构的峰27.9°。FTIR 分析官能团。CV 研究了比电容。此外，我们研究了这些有机染料 MO 97.3%、MB 91.1% 和 Rh-B 99.6% 的效率。这些效率是通过改变染料负载量而获得的。因此，g-C3N4 可以作为 MO、MB 和 Rh-B 等污染物用于水净化的潜在候选物。
