摘　　要：将电纺丝法制备得到的锐钛矿相TiO2在氨气中煅烧,成功制得掺氮TiO2纳米纤维,在可见光下对罗丹明的降解表明具有可见光光催化活性。Ag-TiO2 nanofibers were fabricated by electrospinning and their phases were studied by XRD. By SEM and QBSD analyses, it is found that after calcination, Ag nano-particles (~35 nm) were uniformly dispersed at the surface of TiO2 nanofibers (diameter of about 150 nm). As the concentration of Ag is increased, these Ag nano-particles play an important role in restraining the formation of anatase TiO2 and promoting the formation of rutile TiO2.
