Three-dimensional assembly structure of anatase TiO2 hollow microspheres with enhanced photocatalytic performance

Three-dimensional assembly structure of anatase TiO2 hollow microspheres with enhanced photocatalytic performance

The pure anatase TiO2 hollow microspheres are synthesized by a one-step template-free hydrothermal route. By defining temperature and time limits, we produce TiO2 hollow microspheres with a fluoride-mediated self-transformation. The surface morphology of TiO2 hollow microspheres was studied by SEM....
