The introduction of nitrogen defects in graphitic carbon nitride (g-C3N4) has the important effect improving its photocatalytic performance. This study employs a simple and environmentally friendly one-step pyrolysis method, successfully preparing g-C3N4 materials with adjustable N3C defect concentrations through calcination urea ammonium acetate mixture. By introducing adjusting band structure, conduction was shifted downward by 0.12 V, overcoming traditional application limitations enabling an innovative transition from enhanced oxidation to reduction capabilities. significantly adsorption activation O2. Characterization results showed that increased specific surface area 44.07 m2/g 87.08 m2/g, enriching reactive sites, while narrowing bandgap 2.41 eV visible light absorption capacity. activity, achieving peak performance 54.8% for tetracycline (TC), approximately 1.5 times original g-C3N4, only 5.4% (49.4%) decrease efficiency after four cycles testing. demonstrates enhances expanding potential applications environmental remediation.
