A photocatalytic reactor is an instrument that uses light energy to accelerate the process of chemical reactions. It is an efficient catalyst that can decompose organic pollutants into harmless substances at room temperature and pressure, so it has a wide range of application prospects in environmental protection, energy and other fields.
The working principle of the photocatalytic reactor is to use light energy to excite electrons from the full orbit to the conduction band to form a photocurrent, which in turn redoxes organic pollutants into harmless substances. This kind of reactor has the characteristics of high energy conversion efficiency, low energy consumption and no pollution, so it has a wide range of application prospects in modern industry and daily life.
The structure and working principle of the photocatalytic reactor are relatively simple, mainly composed of a light source, a reactor body and a catalyst. The light source generally adopts ultraviolet lamp or LED lamp, which provides the necessary light energy for the reactor. The main body of the reactor is generally made of corrosion-resistant, light-transmitting materials, and the inside is equipped with a catalyst, which is generally an oxide such as titanium dioxide. When organic pollutants enter the reactor, the catalyst redoxes them to harmless substances when illuminated by a light source.
Photocatalytic reactors have a wide range of applications and can be used to treat various organic pollutants such as volatile organic compounds, formaldehyde, ammonia, etc. In the field of environmental protection, it can be used in air purifiers, automobile exhaust treatment devices, etc.;In the energy sector, it can be used in fuel cells, photoelectrochemical cells, etc. In addition, photocatalytic reactors can also be used to synthesize organic compounds, prepare high-purity gases, etc.
In short, the photocatalytic reactor is a kind of high-efficiency, environmentally friendly and energy-saving chemical reactor, which has a wide range of application prospects. With the continuous development of science and technology, the performance and efficiency of photocatalytic reactors will continue to improve, and the application range will continue to expand.
