Tailored fabrication of TiO2/In2O3 hybrid mesoporous nanofibers towards enhanced photocatalytic performance

In present work, we report the fabrication of mesoporous TiO2/In2O3 nanofibers photocatalyst via the combination of electrospinning and hydrothermal method, in which In2O3 were uniformly grown on electrospun TiO2 nanofibers. The mass loading of In2O3 nanostructures and mesoporous nanostructure could be easily controlled by adjusting raw materials weight of In2O3 within the hydrothermal solutions. The as-prepared photocatalyst were also employed to study their photocatalytic performance for organic decomposition. It is found that TiO2/ In2O3 composites showed significantly enhanced photocatalytic efficiency as compared to that of pristine TiO2 and In2O3 photocatalysts for RhB degradation. The enhanced performance could be attributed to the combined effects of the extended visible-light response range, efficient separation of photo-excited charge carriers and increased reaction active sites.
