Nitrogen oxides (NOx) play a significant role in reducing urban air quality, often playing a role in contributing to photochemical smog pollution events. This Healthy Urban Environments pilot project seeks to develop a coating to enable the front surfaces of photovoltaic (solar) panel installations to actively remove NOx from the urban atmospheres.

Researchers will conduct laboratory evaluations of the viability of commercial grade TiO2 as an agent for photocatalytic reduction of NOx particles. This will be accomplished by developing a photochemical flow-through test system with NOx analyzers installed upstream and downstream to measure the efficiency of the system to remove NOx particles. Once validated, the same system will be used to evaluate a range of TiO2 photocatalysts to determine the most effective option for real-world deployment.
