Degradation effect of temperature variation and dye loading g-C3N4 towards organic dyes

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 (002). 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.
