Laser** water molecule hydrogen production technology is a technology that uses laser energy to break down water molecules to produce hydrogen and oxygen. The main principle of this technology is to irradiate water molecules with lasers, which break the bonds of the water molecules and produce hydrogen and oxygen.
Specifically, when the laser is irradiated on the semiconductor, when the energy of the radiation is greater than or equal to the bandgap width of the semiconductor, the electrons in the semiconductor are excited to jump from the valence band to the conduction band, while the holes remain in the valence band, so that the electrons and holes are separated, and then the water is reduced to hydrogen at different locations in the semiconductor, and the water is oxidized to oxygen at the same time.
Laser** water molecule hydrogen production technology is an emerging hydrogen production technology, and the main advantages of this technology include:
1.Efficient
Laser** water molecule hydrogen production technology can more efficiently decompose water molecules into hydrogen and oxygen. Studies have shown that hydrogen and oxygen yields increase with laser frequency.
2.Environmentally friendly
Laser** water molecule hydrogen production technology does not require additional catalysts, and only needs to use laser to achieve the complete solution of water molecules and generate high value-added products such as hydrogen and oxygen.
3.Simple
The operation process of laser ** water molecule hydrogen production technology is relatively simple, and the decomposition of water molecules can be achieved by simply irradiating the laser into the water.
4.Clean
Since the laser ** water molecule hydrogen production technology does not require additional catalysts, it does not produce harmful by-products and is a very clean hydrogen production method.
5.High yield
The higher yield of the laser** water molecule hydrogen production technology means that it can produce hydrogen more efficiently to meet the growing demand for hydrogen. However, despite the above advantages, there are still some challenges in practical applications, such as the efficiency of lasers and how to better control laser irradiation in actual operation.
However, although the laser water molecule hydrogen production technology has a certain theoretical basis, there are still some challenges in practical application. For example, lasers have a maximum efficiency of about 55%, excluding the loss of laser light in transmission. In addition, the laser also drives the negative ions produced and consumes energy. Therefore, how to improve the efficiency of the laser and reduce the loss of the laser in the transmission process are important problems faced by the laser water molecule hydrogen production technology in practical applications.
There is no clear breakthrough in the technology of laser water molecule hydrogen production, although it is theoretically feasible, but there are still many technical and economic problems to overcome in practical application.
