Abstract
A series of novel sodium persulfate (Na2S2O8) modified g-C3N4 photocatalysts were prepared in this study to enhance nitrogen fixation. Characterization results found that the type of precursors and the mass ratio affect the crystal structure, morphology, and optical properties of the modified g-C3N4. The photocatalysts exhibited considerable nitrogen vacancies (NVs) depending on the nature of the different precursors and their mass ratios to Na2S2O8. In addition, the production rate of ammonia of the modified g-C3N4 was significantly higher than that of pure g-C3N4 under optimal conditions. The four cycles show modified g-C3N4 excellent stability. Combined with the results of pH test, the possible mechanism of the photocatalytic nitrogen fixation process using modified g-C3N4 was proposed.
