Heterogeneous photocatalytic oxidation (PCO) has already shown as a promising air purifying technology for indoor air quality improvement. This article addresses the PCO of nitric oxide (NO), one of the typical indoor air pollutants, employing a novel wall paper as substrate for the coating of a carbon modified TiO2 and visible light as light source. A kinetic model is proposed to describe the PCO of NO with a typical initial concentration under indoor air conditions
