UV-LED innovation in the field of photocatalysis

  With growing global attention to environmental protection and sustainable development, photocatalysis, as a green and efficient environmental governance technology, is gaining increasing attention. UV-LEDs (ultraviolet light-emitting diodes), the ideal light source for photocatalytic reactions, are driving innovation and application in photocatalytic technology thanks to their high efficiency, environmental friendliness, and strong controllability.

  The core of photocatalytic technology is to use light energy to excite catalysts (such as titanium dioxide) to generate electron transitions, thereby driving chemical reactions. Traditional photocatalytic technology typically uses mercury or xenon lamps as light sources, but these light sources suffer from high energy consumption, short lifespans, and spectral impurities. UV-LEDs, as a new type of semiconductor light source, offer the following unique advantages: UV-LEDs have significantly higher electro-optical conversion efficiency than traditional mercury lamps and can produce high-intensity UV light with lower energy consumption. They typically have a lifespan of tens of thousands of hours and stable performance, making them suitable for long-term operation. The wavelength of the emitted UV light can be precisely controlled to optimize the efficiency of the photocatalytic reaction. Their small size makes them easy to integrate into various devices, making them suitable for applications in complex scenarios.

  In the field of water treatment, photocatalytic technology can effectively degrade organic pollutants in water, such as phenol, dyes, and pesticides. UV-LEDs, as light sources, can stimulate catalysts (such as TiO₂) to produce reactive oxygen species, thereby decomposing organic pollutants into carbon dioxide and water.

   In the field of air purification, UV-LED photocatalytic technology can effectively decompose harmful gases and particulate matter in the air. For example, a Dutch environmental protection company has developed a UV-LED-based photocatalytic air purification device. This device uses a TiO₂ catalyst and a UV-LED light source to break down harmful gases such as formaldehyde and volatile organic compounds (VOCs) in the air into harmless substances. Compared with traditional activated carbon adsorption technology, this technology not only removes harmful gases but also kills bacteria and viruses in the air, achieving higher purification efficiency.

  In the industrial sector, UV-LED photocatalytic technology is being used to treat surface contaminants. For example, a South Korean automobile manufacturer has introduced a UV-LED-based photocatalytic surface cleaning system. This system uses UV-LED light to activate a TiO₂ catalyst, breaking down organic contaminants such as oil and dirt on the vehicle surface into harmless substances. Compared to traditional chemical cleaning methods, this technology is more environmentally friendly and requires no detergents, making it suitable for large-scale industrial applications.

  UV-LED photocatalytic technology will play a greater role in environmental governance, resource utilization, and industrial testing. The promotion and application of this technology will not only effectively address environmental pollution issues but also provide a new technological path for sustainable development.
