摘要：

Mn-doped amorphous TiO2 photocatalyst powders containing 0.1% and 1% Mn (w/w) were tested for oxidation of NO under indoor-like illumination conditions. Only the catalyst containing 0.1% Mn was able to degrade NO efficiently upon irradiation with the indoor-like source (visible light), whereas the one containing 1% Mn was active under solar-like irradiation. Preliminary results from addition of the 0.1% Mn-TiO2 photocatalyst to calcareous filler commonly used in the formulation of building products demonstrate its ability, in this form too, to degrade NO at concentration levels typically found in indoor environments.
