Abstract

We report on the visible-light responsive Bi-doped In2O3 nanospheres, which were synthesized via a simple solvothermal reaction between Bi(NO3)3•5H2O and In(NO3)3•4.5H2O in the presence of absolute ethanol and ethylene glycol by adding urea and annealing it at 400 0C. The effects of experimental parameters on the nanostructural and morphological behavior of Bi-doped In2O3 nanospheres were discussed. Photocatalysts exhibit high activity owing to both the unique structural characteristics and the Bi ion doping. The doped Bi ion inhibits recombination rate of photo-induced carriers. Furthermore, the effects of Bi ion can be clearly drawn, and the degradation ratio of Bi-doped In2O3 nanospheres reaches 80.81%, which is reasonable to expect the obvious Bi ion dependent activity.
