“Smog Eating” Titanium Dioxide Surfaces
On 21st September 2025, the Delhi government announced that it is set to test titanium dioxide (TiO₂)-based “smog-eating” coatings on roads, pavements, and public spaces to reduce harmful pollutants such as nitrogen dioxide (NO₂) and hydrocarbons.
- Field trials will be conducted in collaboration with a reputed scientific institution, with monthly progress reports and a final evaluation within six months.
How It Works
- Photocatalytic Process: TiO₂ reacts with sunlight to break down air pollutants into less harmful compounds.
- Durable Coating: Chemically stable and compatible with conventional construction materials, allowing long-term use.
- Controlled Trials: Effectiveness, safety, and cost-efficiency will be rigorously measured under real-world conditions.
