ABSTRACT
Semiconductor photocatalysts have important applications in renewable energy and environment fields. To overcome the serious drawbacks of low efficiency narrow light-response range most stable semiconductor photocatalysts, many strategies been developed past decades. This review attempts to provide a comprehensive update examination some fundamental issues titania (TiO2)-based such as crystal growth, doping heterostructuring. We focus especially on recent progress exploring new design TiO2-based with unique structures properties, elucidating chemical states distribution dopants doped TiO2, designing fabricating integrated heterostructure different charge-carrier transfer pathways, finally identifying key factors determining photocatalytic titania-based photocatalysts.
