Delhi Launches Photocatalytic Coating Trials to Combat Air Pollution

What's the News?

• The Delhi Government has partnered with IIT Madras to conduct a pilot study on smog-eating photocatalytic coatings for city infrastructure .
• A Memorandum of Understanding (MoU) was signed between the Delhi Environment Department and IIT Madras for this initiative .
• The six-month study will test coatings on roads, pavements, buildings, and tiles across selected locations in Delhi .
• This initiative aims to explore innovative, low-cost solutions to reduce air pollutants, particularly nitrogen oxides (NOx) .

Photocatalytic Coating Technology

• Working Mechanism: The coating uses Titanium Dioxide (TiO₂) as a photocatalyst that activates under sunlight .
• Chemical Process: When exposed to light, TiO₂ triggers a reaction that breaks down harmful pollutants into less toxic compounds .
• Target Pollutants:
  • Nitrogen Dioxide (NO₂) from vehicular emissions
  • Volatile Organic Compounds (VOCs) from industrial sources
  • Hydrocarbons from fuel combustion

Study Objectives & Implementation

• Field Trials: Real-world testing on Delhi's roads and infrastructure under actual traffic and pollution conditions .
• Data Collection: Analysis of traffic patterns, pollution levels, and coating performance .
• Goals:
  • Identify durable and affordable deployment methods .
  • Assess long-term effectiveness in Delhi's climate conditions .
  • Determine scalability for city-wide implementation .

Significance for Urban Air Quality

• Innovative Approach: First major trial of smog-eating coatings in an Indian metropolitan city.
• Complementary Measure: Works alongside existing policies like GRAP (Graded Response Action Plan) and odd-even schemes.
• Environmental Benefits:
  • Reduces ground-level ozone formation
  • Lowers respiratory health risks for citizens
  • Contributes to National Clean Air Programme (NCAP) targets
• Cost-Effective: Lower maintenance compared to traditional air purification systems .

Additional Information

• Related Air Pollution Initiatives in Delhi:
  • Commission for Air Quality Management (CAQM): Statutory body for NCR air quality oversight
  • National Clean Air Programme (NCAP): Targets 20-30% reduction in PM concentrations by 2024
  • GRAP (Graded Response Action Plan): Emergency measures based on AQI levels
  • Electric Vehicle Policy: Promotes EV adoption to reduce vehicular emissions
• Global Precedents:
  • European Union: Tested photocatalytic coatings in highway tunnels with 80% NOx reduction
  • UK Department for Environment: Studied paints and surfaces for NOx removal
  • Denmark: Conducted field trials showing 14-21% NOx reduction
