The present study aims to analyze the potential of a developed functional wallcovering applying the technology of photocatalysis for the indoor air quality improvement. The effect of the amount of layers of the coating and nano-silica incorporation in the formulation of the coating on the air pollutants removal efficiency is evaluated. The photocatalytic efficiency is assessed on the lab scale by the degradation of an inorganic pollutant - nitric oxide - using a plug-flow experimental set-up. Experimental conditions to simulate indoor air environment are applied. A pre-treatment method is found to be necessary in order to promote the photocatalytic efficiency. All coatings exhibited high photocatalytic efficiencies for nitric oxide degradation under applied experimental conditions. The photocatalytic efficiency is positively affected by the nano-silica addition and by the number of layers of the coating. The best performing coatings, able to degrade 69% of nitric oxide, are those containing nano-silica applied in two layers. This work confirms the potential of the photocatalysis for the indoor air quality improvement.</p
