Photocatalytic concrete with TiO2 can help clean up polluted city air by breaking down harmful gases like NO and NO2 from car exhaust. Scientists tested how well this concrete works under different conditions like humidity and sunlight. They found that the concrete can effectively degrade these pollutants when exposed to sunlight, helping to improve air quality in urban areas.
