New Paint Technology Cleans Walls and Improves Air Quality

In a groundbreaking development, researchers from TU Wien and the Università Politecnica delle Marche in Italy have created titanium oxide nanoparticles that can clean walls and improve indoor air quality. These nanoparticles are capable of breaking down pollutants when mixed with standard paint and exposed to sunlight.

The study, published on, highlights the innovative technology that allows painted walls to not only clean themselves but also improve indoor air quality by eliminating pollutants. This can help combat the issue of “sick building syndrome,” where poor air quality negatively affects the health of those inside a building.

Professor Günther Rupprechter from TU Wien explained that titanium oxide nanoparticles have the ability to bind and break down a wide range of pollutants, making them particularly useful for this application. The research showed that 96% of air and wall pollutants can be removed by exposing them to simple sunlight with the help of these nanoparticles.

One of the study’s authors, Qaisar Maqbool, highlighted that detailed analysis of the particles and their behavior before and after being added to wall paint was conducted to better understand the process. Further research is planned with the goal of creating a commercially available paint product using this technology.
