摘要：

TiO2 nanomaterials have attracted tremendous interest in photocatalytic hydrogen generation. Herein we report unique colored anatase TiO2 hollow spheres consisting of crystalline-inner shell/amorphous-outer shell structured nanocrystallites, which exhibit remarkably enhanced photocatalytic performances for water splitting. The optimized TiO2 spheres delivered a H-2 production rate of 0.182 mmol g(-1) h(-1), which was 2 times higher than that of pristine TiO2. The enhanced activity can be ascribed to the generation of oxygen vacancies and Ti3+ sites.
