摘要

Our research focuses on synthesizing sulfamic acid (SA) loaded polymeric carbon nitride (PCN) using a facile thermal polymerization method for enhanced photocatalytic activity and supercapacitor application. The photocatalytic activity of synthesized sulfamic acid- polymeric carbon nitride (xSA-CN) catalysts were investigated for photocatalytic degradation of tetracycline hydrochloride (TCH) as model pollutant. The optimized 20SA-CN catalyst showed highest activity for degradation (94.4%) of TCH compared to pristine PCN and other xSA-CN composites under visible light irradiation. The 20SA-CN catalyst was also employed for electrode preparation and the 20SA-CN electrode showed specific capacitance (Cs) of 22.61 Fg−1 at a current density of 0.5 mA. cm−2 which is significantly higher than that of pristine PCN. The 20SA-CN catalyst showed a good reusability and stability, and it appears to be an efficient, and environmentally friendly catalyst. The enhanced photocatalytic activity of the 20SA-CN is ascribed to the increase in surface area and improved charge transfer dynamics.
