项目简介：

Titanium dioxide (TiO₂) has been widely used for renewable energy applications such as photocatalytic hydrogen generation, photocatalytic CO₂conversion, and photocatalytic environmental cleanings. Its ability to absorb sunlight plays a key role in the overall efficiency for these applications. However, it is a white material, with a large bandgap, and only absorbs light in the ultraviolet (UV) region. This limits its overall efficiency as the UV light only accounts for less than 5% of the whole solar spectrum. Here, I would like to introduce our work on how to turn white titanium dioxide into black, in order to improve its efficiency in renewable energy applications. The fundamental materials and physiochemical characterizations will be discussed in details. In addition, their applications in lithium-ion rechargeable battery and microwave absorption will be introduced, along with other recent work.
