Efficient use of solar energy | 'Password' | Deciphering

How to use solar energy's 'password' has been deciphered. The latest issue of the international journal The British Chemical Society Review published an important breakthrough in the field of solar thermal fuel. The team of Professor Feng Wei of Tianjin University systematically explained the first time in the world. The important role of nitrogen benzene in solar thermal fuel is a disruptive technology that contributes to the efficient use of solar energy, etc. This research is expected to open a new chapter in the efficient use of solar energy.

Solar energy is inexhaustible, and it is one of the most abundant energy sources in the natural world. Achieving efficient use of solar energy is also the key to solving energy problems. At present, there are still inefficiencies and scattered radiation in human development and utilization of solar energy. Unstable energy storage and other defects. Ideal solar thermal fuel will achieve reversible energy conversion and storage in a single material system, with zero emissions, easy transportation, recyclability, regenerability and on-demand release in heat. Solar thermal fuel has thus become an important target for scientists around the world.

The Fengwei team has long been committed to the development of solar thermal materials. It is one of the first research teams in the world to focus on the research of organic molecular photothermal energy. In the study, they found that the azobenzene-carbon nanotube structure is the basic molecular structure for realizing photothermal energy. In this structure, azobenzene is expected to become a thermal material storage, releasing the smart 'switch' and 'memory' of solar energy. The azobenzene molecular structure has a unique 'light-induced reversible structural transition property', which can pass the optical switch molecular structure Conversion and spatial rearrangement to store energy from solar radiation, and then release energy in the form of heat, is an important potential material for light-heat storage and controlled release.
