Overview
- The Delhi government signed an MoU with IIT Madras to investigate photocatalytic materials designed to neutralize urban air pollutants.
- Professor Somnath C. Roy will lead the project, beginning with smog-chamber experiments to measure pollutant abatement under controlled conditions.
- Field assessments in Delhi will test coatings and materials across concrete, asphalt, glass, metal panels and road surfaces to gauge effectiveness and durability.
- Researchers will compare integration methods including mixing into concrete or asphalt, applying surface coatings, and deploying rooftop or streetlight-mounted panels.
- Officials said findings will guide policy, with potential deployment during peak smog months if results are positive, aligning with a preference for innovation over blanket bans.
