中文摘要:
      采用浸渍-热聚合法制备CDs/ZnO/g-C3N4复合材料,考察其对罗丹明B的光降解效率。利用 XRD、TEM、XPS、UV-Vis DRS、FI-IR等手段对催化剂进行表征和评价。结果表明:CDs/ZnO/g-C3N4仍保持石墨相g-C3N4的晶型结构,三元组份相互协同作用使CDs/ZnO/g-C3N4表现出优异的光催化性能,其降解罗丹明B的效果优于单体g-C3N4、ZnO及ZnO/g-C3N4,脱色率可达到70%左右。
英文摘要:
      The CDs/ZnO/g-C3N4 composites were prepared by impregnation-thermal polymerization method, and the photodegradation efficiency of Rhodamine B was investigated. The catalyst was characterized and evaluated by means of XRD, TEM, XPS, UV-Vis DRS and FI-IR. The results show that CDs/ZnO/g-C3N4 still maintains the crystal structure of g-C3N4 in the graphite phase, and the ternary components synergistically make CDs/ZnO/g-C3N4 exhibit excellent photocatalytic properties, which degrade Rhodamine B. The effect is better than monomer g-C3N4, ZnO and ZnO/g-C3N4, and the decolorization rate can reach about 70%.
