Brief introduction of project results

The energy problem has pushed the utilization of solar energy to the forefront of science and technology research. In various schemes of solar energy utilization, the process of photocatalysis to realize the conversion of solar energy into chemical energy is a very important research field. 

"Photocatalysis" involves first reducing carbon dioxide into hydrocarbons such as methane and ethane or splitting water into hydrogen, a clean energy source. In this way, we will not only solve the global energy crisis, but also realize the "carbon cycle", which will take the excess carbon dioxide in the atmosphere and put it to real use in industrial life.

Titanium dioxide is one of the most popular photocatalytic materials this year. It has a high specific surface area, stable physical and chemical properties, and defect control Because it can efficiently regulate the electronic band structure of the photocatalyst, carrier migration and construction of surface active sites and can build a variety of efficient composite photocatalytic materials, its excellent interface performance enables it to be assembled into devices in different application environments. From what has been said above, it has a wide range of application and broad application prospects. Importantly, titanium dioxide also has good environmental compatibility and can achieve deep conversion of solar energy.
