The practical application of LED photocatalytic reactors is widespread and significant, particularly in the fields of environmental protection, energy conversion, and organic synthesis. Below are some key areas where LED photocatalytic reactors have shown promise:

1. Environmental Protection

• Automobile Exhaust Degradation: LED photocatalytic reactors can effectively degrade harmful substances in automobile exhaust, such as nitrogen oxides, carbon monoxide, and volatile organic compounds. Under light conditions, these substances can be converted into harmless substances, significantly reducing environmental pollution from automobile emissions.

• Carbon Dioxide Reduction: LED photocatalytic reactors have potential applications in carbon dioxide reduction processes, contributing to the mitigation of global warming and climate change.

2. Energy Conversion

• Methane Conversion: LED photocatalytic reactors can activate methane molecules, enabling efficient conversion under mild conditions to generate valuable chemical products. This not only improves methane utilization efficiency but also reduces pollution generated during traditional methane conversion processes.

• Petroleum Catalytic Cracking: LED photocatalytic reactors offer advantages in petroleum catalytic cracking by enabling efficient cracking at relatively low temperatures and pressures, thus reducing energy consumption and pollution compared to traditional methods.

3. Organic Synthesis

• Photocatalytic Synthesis: LED photocatalytic reactors are used for various organic synthesis reactions, including the synthesis of drugs, materials, and other chemicals. The ability to control the intensity and duration of light exposure allows for precise control over the reaction rate and product selectivity.

• Gas-Solid Reactions: Advanced gas-solid LED photocatalytic reactors have been developed for organic syntheses and environmental applications. These reactors couple positive aspects such as wide exposure of the catalyst to radiation and the effective use of UV LEDs, which are long-lasting, robust, small in size, and high in light efficiency.

4. Design and Optimization

• Double-Sided LED Light Source: The design of double-sided LED light sources for photocatalytic reactors enhances illumination uniformity and coupling efficiency, which are crucial for the efficient operation of the reactor.

• Material Innovations: The use of advanced materials such as metal-organic framework materials (MOFs) as photoelectric materials further improves the performance of LED photocatalytic reactors by increasing reaction efficiency and providing more possibilities for reactor optimization.

In summary, LED photocatalytic reactors have a wide range of practical applications, offering significant advantages in environmental protection, energy conversion, and organic synthesis.
