Abstract

Photocatalytic technology has become a hot spot to solve environmental and energy problems. Among many photocatalysts, TiO2 has attracted much attention for its low cost, high stability and excellent photocatalytic activity. With the rapid development of nanotechnology, scientists are deepening their research on the core–shell TiO2 which has a special morphology and structure. It can be a multi-layer composite of multiple components or multiple reflections of light on the inner surface which greatly affects the photocatalytic activity of TiO2. Therefore, a variety of core–shell TiO2 nanomaterials have been designed and prepared to solve the problem of insufficient performance of TiO2 in the photocatalytic process. This chapter reviews the research progress of various core–shell TiO2 nanomaterials in the field of photocatalysis. We discussed the design, preparation and application of the materials in pollutant degradation, hydrogen production and carbon dioxide emission reduction. Finally, the development prospects of core–shell TiO2 nanomaterials in the field of photocatalysis are prospected.
