摘要
使用二氰二胺和九水合硝酸铁制备了铁掺杂石墨相氮化碳(Fe-CN),测试分析了该材料的官能团和化学键、晶型结构、比表面积和平均孔容,研究了不同因素对材料性能的影响。结果表明:在催化剂投加量2 g/L、铁掺杂质量分数为1%、光照强度300 mW/cm^(2)、底物浓度10 mg/L、pH=7、反应120 min的条件下,Fe-CN的光催化效果最好,对RhB的去除率为99.3%,且材料具有较好的稳定性。
Fe-doped graphitic carbon nitride(Fe-CN)was synthesized via Dicyandiamide and Ferric nitrate nonahydrate.Its functional groups,crystal structure,BET surface area,and porosity were characterized,and photocatalytic performance was evaluated under varying conditions.Optimal results(99.3%RhB removal)were achieved at 2 g/L catalyst,1%Fe doping,300 mW/cm^(2) irradiation,10 mg/L RhB,pH=7,and 120 min reaction,demonstrating excellent stability.
