The photo-catalysis is a promising method for the degradation of harmful organic pollutants existing in the wastewater. In this research work, degradation of organic pollutants (dyes) have been done proficiently for the wastewater treatment applications. The synthesized steady graphitic carbon nitride (g-C3N4) nanorods have been examined by various sophisticated characterization techniques such as XRD, SEM, EDS, TEM, UV-Vis and PL. The hexagonal phase of g-C3N4 has been showed in XRD analysis. SEM shows that the morphology of g-C3N4 consists of aggregated nanorods. The EDS depicting only two peaks which are carbon and nitrogen and nitrogen without impurities. According to the study of UV-Visible and PL, 2.77 eV band gap has been observed showing consistency. The steady g-C3N4 nanorods have been used for the degradation of prominent organic dyes such as: methylene orange (MO), methylene blue (MB) and rhodamine-B (Rh-B) for treatment of wastewater which is a dire need. The effect of catalyst mass loading and time have been studied for this purpose. This research depicted that the anion (•O2−) and holes (h+) are attributed to the degradation of organic pollutants. whose Rh-B, MB and MO dyes. Research based a tentative photocatalytic mechanism has also been proposed for waste treatment purpose.
