Yes, nanotechnology plays a significant role in air purification. Nanoparticles such as titanium dioxide (TiO2) can be used in photocatalytic air purifiers. When exposed to UV light, TiO2 generates reactive oxygen species that can break down pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx) into less harmful substances. Additionally, metal-organic frameworks (MOFs) are being researched for their ability to capture and store gases such as CO2.
