Can cast iron outdoor sofas be coated with photocatalytic materials for air purification?

Cast iron outdoor sofas are known for their durability and classic appeal, but can they be enhanced with photocatalytic coatings for air purification? Photocatalytic materials, such as titanium dioxide, react with sunlight to break down pollutants, making them a promising solution for cleaner outdoor air.

Applying these coatings to cast iron requires careful preparation to ensure adhesion and longevity. The porous surface of cast iron may need priming, and the coating must withstand weather conditions. While feasible, the effectiveness depends on proper application and exposure to UV light.

This innovation could transform outdoor furniture into eco-friendly assets, combining aesthetics with environmental benefits. However, long-term performance and maintenance should be considered before widespread adoption.
