中文摘要:
      采用酸水热后处理法制备了具有优异光催化合成双氧水性能的硫酸根改性石墨相氮化碳纳米棒催化剂。采用XRD、N2吸附脱附、UV-Vis、FTIR、SEM、XPS、TPD、EIS及PL对催化剂进行表征。结果显示:硫酸根的引入改变了催化剂的结构性质,光学性质和氧气吸附能力。所制备的硫酸根改性氮化碳催化剂的双氧水平衡浓度为2.7 mmol/L,是纯氮化碳的2.7倍。
英文摘要:
      In this work, sulfate-modified graphitic carbon nitride nanorods as efficient photocatalyst for H2O2 production was prepared via acid-hydrothermal method. XRD, N2 adsorption, UV-Vis, FTIR, SEM, XPS, TPD, EIS, and PL were used to characterize the obtained catalysts. Sulfate modification not only influences the morphology, structure property and optical property, but also promotes the O2 adsorption ability. Sulfate modified g-C3N4 catalyst shows the H2O2 concentration of 2.7 mmol?L-1, more than 2.7 time higher than that of neat g-C3N4.
