题目: Tuning Titanium Dioxide Nanomaterials for Renewable Energy and Sustainable Environment Applications
The rapid depletion of the fossil fuel reserves, the increase of green-house gas emissions and other environmental pollutions, bring up an urgent need for the development of renewable and clean energy sources. The ability to use sunlight to produce fuels such as H2 and electricity from abundant, non-toxic resources, and to decompose environmental pollutions with benign catalysts, would revolutionize our civilization. Here, I would like to present our study on how to turn white titanium dioxide into yellow and black titanium dioxide, in order to efficiently remove pollutions and generate hydrogen from water. The fundamental materials and physiochemical characterizations will be discussed in details.
