A photocatalytic paint for air decontamination was tested under different operation modes and conditions in a reaction chamber that simulates an indoor room. A first principles model able of predicting the outlet concentration of the pollutant from the continuous reaction chamber or the evolution of the reactant concentration operating the chamber in batch mode was developed. The main inputs for the model were: i) optical properties of the paint, ii) radiation field in the chamber, iii) dimensions and operating conditions of the reaction chamber, and iv) intrinsic photocatalytic kinetics of pollutant degradation previously determined. The developed model showed a very good agreement with the experimental measurements. Given the input information required by the model, the proposed methodology can be adopted to simulate the air decontamination in real applications of photocatalytic paints in indoor environments.
