| Abstract: | Mo-doped TiO2 nanoparticles were prepared via Sol-Gel method and nano-film by dip-doped method.They were characterized by XRD,XPS,SEM.The photocatalytic activity was investigated by degradation of RB.Effects of calcination temperature,keeping-warm time and Mo doping content on crystal lattice distortion,grain size,crystal phase and photocatalytic activity were investigated.The results showed that most of Mo6+ took the place of Ti4+ in the crystal lattice of TiO2,which led to crystal lattice distortion,restr... |
