Abstract

Sodium hypophosphite induced a simultaneous P doping and hollowing process of TiO₂ spherical nanostructures and produced P-doped hollow spherical nanostructures via a simple one-step hydrothermal method. The as-synthesized P-doped hollow spherical nanostructures demonstrated significantly enhanced photocatalytic activity for MB degradation compared to the undoped TiO₂ and P25 under sunlight irradiation.
