Photocatalytic degradation of NO/NO gas injected into a 10-m experimental chamber.

This paper investigates a new test method to assess the photocatalytic activity of plasterboards coated with a TiO dispersion under real-world conditions. The degradation of nitrogen oxides NO (NO and NO) is studied and the photocatalytic efficiency under UV illumination is evaluated in a 10-m room after a constant gas injection. Two ultrafine TiO dispersions are used: 0.
