Volatile Organic Compounds (VOCs) are a class of organic chemicals with high volatility, widely present in daily life and industrial production. VOCs include a variety of substances such as formaldehyde, benzene, and toluene, which pose potential hazards to the environment and human health.

Hazards of VOCs

1. Environmental Impact: VOCs react with other chemicals in the atmosphere, leading to the generation of ozone and the formation of smog, exacerbating air pollution issues.

2. Health Risks: Some VOCs are toxic, and prolonged or high-concentration exposure may cause headaches, eye and throat irritation, and even increase the risk of cancer.

3. Ecological Damage: VOCs can be transported through the atmosphere to distant areas, affecting soil and water ecosystems and posing a threat to biodiversity.

Defense Strategies

1. Source Control: Choose raw materials and products with low VOC emissions, such as using water-based paints instead of solvent-based paints.

2. Ventilation Improvement: Strengthen ventilation facilities in places where VOCs may be released, such as paint shops and dry cleaners, to reduce VOC concentrations.

3. Personal Protection: Wear appropriate protective equipment, such as masks and goggles, when in environments exposed to VOCs.

The governance of VOCs is a complex environmental issue that requires the comprehensive application of strategies such as source control, process management, and end-of-pipe treatment. Catalysts, as an efficient VOCs governance technology, play an irreplaceable role in reducing VOC emissions and improving air quality. With the continuous advancement of catalyst technology and the increasing environmental awareness, we can expect to more effectively control the hazards of VOCs in the future, protecting the environment and human health.

Role of Catalysts in VOCs Governance

1. Efficient Conversion: Catalysts significantly improve the conversion efficiency of VOCs, achieving efficient catalysis even at lower temperatures.

2. Selective Catalysis: Specific catalysts with tailored activity can be developed for particular VOCs, enhancing governance efficiency.

3. Long-lasting Stability: High-quality catalysts possess excellent thermal stability and resistance to poisoning, maintaining efficient catalytic activity over extended periods.
