Photocatalytic activity of Ag/g-C۳N۴ for Degradation of Methyl orange Dye under visible-light irradiation

We present the development of a novel photocatalyst system based on graphitic carbon nitride (g-C۳N۴) nanosheets decorated with silver nanoparticles, and was used to catalyze of degradation of Methylene orange (MO) under visible-light irradiation. The silver nanoparticles were synthesized using the green method of Rheum neyshabourense sp. Remarkably, Ag/g-C۳N۴ nanocomposite could degrade ۹۲% of MO. The results showed that methylene orange at ۲۰ mg L-۱ was best degraded after ۸۰ min at ۰.۰۶ g L-۱ Ag/g-C۳N۴, pH of ۵. The unique electronic configuration of graphitic carbon nitride (g-C۳N۴) establishes it as a compelling candidate for visible-light photocatalysis. To enhance its performance, researchers have engineered g-C۳N۴ by integrating the Ag particles, resulting in a substantial improvement in its photocatalytic efficiency. This study provides a new insight for the preparation of highly efficient photocatalysts for the degradation of organic dyes. The produced catalyst was characterized using a variety of techniques such as FT-IR, SEM and DRS.
