| چکیده مقاله |
| In response to the urgent global issue of environmental pollution, particularly water contamination by high-chroma organic pollutants, there has been a growing focus within the scientific community on developing advanced materials for efficient pollutant removal. One such promising material is graphene-like carbon nitride (g-C₃N₄), which possesses excellent chemical stability, high surface area, and photocatalytic properties. This essay delves into the facile synthesis of g-C₃N₄-x for effectively removing high-chroma organic pollutants from water, exploring its potential applications, advantages, and prospects. Additionally, a g-C3N4-x photocatalyst has been synthesized in this study by introducing nitrogen vacancies through a one-step reduction process. The optimized g-C3N4-x catalyst exhibited a superior MB yield of 73% under visible light, representing a 4.5-fold increase compared to the bulk g-C3N4 catalyst. This advancement is attributed to the synergistic effects of nitrogen vacancies (Nv) defects, which enhance light absorption, facilitate electron-hole pair separation, and increase the number of active sites on the catalyst surface. In our research, we successfully created a g-C3N4-x photocatalyst by incorporating nitrogen vacancies using a one-step reduction technique. The optimized g-C3N4-x catalyst displayed an impressive 73% MB yield under visible light, 4.5 times higher than the standard g-C₃N₄ catalyst. This improvement is attributed to the synergistic effects of nitrogen vacancies (Nv) defects, which enhance light absorption, aid in separating electron-hole pairs, and increase the number of active sites on the catalyst's surface. |
