摘　　要：通过静电纺丝技术和高温碳化制备了石墨烯/镧共掺杂TiO2纳米纤维。采用扫描电子显微镜、X-射线衍射仪、红外光谱仪及紫外分光光度计对纳米纤维的形貌、结构和光催化性能进行了表征和测试。结果表明,石墨烯的掺杂可以提高TiO2纳米纤维的光催化性能,当石墨烯掺杂量为0.1 g时,TiO2纳米纤维的光催化性能较优。Graphene/La3+co-doped TiO2 nanofibers are prepared by electrospinning technique and high temperature carbonization.Themorphology,structure and photocatalytic properties nanofibers are characterized and tested by scanning electron microscope,X-raydiffractometer,infrared spectrometer and ultraviolet spectrophotometer.The results show that the doping of graphene could improve thephotocatalytic properties of TiO2 nanofibers.when the doping content of graphene is 0.1 g,the photocatalytic performance of TiO2 nanofibersis the best.
