From Laboratory Promise to Real-World Performance: Assessing The Deployability of Nano-Tio2 in Self-Cleaning and Air-Purifying Building Material
Abstract
Nano-titanium dioxide (TiO?) is currently being strongly sold as a miracle product in the manufacture of air cleaning, cleaning air in buildings in cities. However, there is a huge disparity between perceived and actual performance of a field-level, critical analysis. Although nano-TiO2 remains the only unquestioned standard photocatalyst due to its unique alkaline stability and bimodal photocatalytic-superhydrophobic activity, its practical operational performance is grossly impaired by three inherent constraints an ultra-environmental response to UV light and soiling akin to all known photocatalysts, extensive scalability demands during manufacturing and cost, and lifecycle immaturity regarding its overall net environmental benefit. This review shows that nowadays the main challenge is not the issue of materials science; it is the issue of practical deployability. The paradigm is thus encouraged to be redefined to revolve around maximizing optimum lab performance to the continuation of its operation in the complex urban settings. Finally, a proper roadmap should be adopted with proper testing plans and industrial standardization and outcome-based policymaking to realize the persuasive vision of nano-TiO2 into an operable tool to improve environmental health in cities.
