*🛡️Smog-Eating Technology*

♟️A photocatalytic technology based primarily on Titanium Dioxide (TiO₂).
♟️Works through coatings applied on roads, pavements, buildings, etc. to neutralize air pollutants.

*💎How it Works?*
♟️TiO₂ acts as a photocatalyst when exposed to sunlight/UV light.
♟️Converts harmful gases like Nitrogen Dioxide (NO₂) & VOCs → into nitrates, CO₂ & water.
♟️Creates a “self-cleaning” effect, breaking down pollutants on contact.

*💎Benefits*
♟️Reduces harmful pollutants (NO₂, hydrocarbons).
♟️Improves public health by lowering toxic air exposure.
♟️Low-maintenance, works passively under sunlight.
♟️Can be integrated with existing urban infrastructure without major disruption.

*💎Challenges*
♟️Needs scientific validation under Indian/local conditions.
♟️Cost-effectiveness of large-scale application still debated.
♟️Concerns about long-term durability of coatings & safe disposal of residues.
