| 摘 要： | 依次用溶剂热法和水热法制备得到暴露(101)晶面的八面双锥体二氧化钛OBP-TiO2和不同碳负载量的N-CDs/OBP-TiO2复合催化剂,以及暴露(001)晶面的纳米片二氧化钛TNS和不同碳负载量的N-CDs/TNS复合催化剂。利用TEM、XRD、XPS等表征手段对这2类复合催化剂的形貌结构、化学成分等作了鉴定。系统研究了碳量子点负载量对可见光降解RhB的光催化性能影响。实验发现,由于N-CDs的加入,均能较大提高2类复合催化剂的光催化性能。(101)高裸露晶面N-CDs/OBP-TiO2比(001)高裸露晶面N-CDs/TNS的光催化活性高。

| Abstract: | Carbon quantum dots doped octahedral bipyramids TiO2 with high exposed(101)reactive facets and carbon quantum dots doped nanosheets TiO2 with high exposed(001)reactive facets were successfully fabricated by facile solvothermal process.The catalysts were characterized using TEM,XRD and XPS measurements.They confirm that the carbon quantum dots were uniformly integrated to TiO2.The catalytic activity of the as-prepared catalysts in degradation of rhodamine B in aqueous solution under visible light irradiation(λ≥400 nm)was systematically investigated.The experiments show that the doping of carbon quantum dots in TiO2 can substantially improve the photo degradation efficiency relative to pure TiO2,both for octahedral bipyramids TiO2 and nanosheets TiO2.Generally,the photodegradation efficiency of(101)facet exposed octahedral bipyramids TiO2 is prevailing over that of(001)facet exposed nanosheets TiO2. |
