Resumen:
Different commercial, visible
light response, TiO2 powders are studied in order to assess their
application in indoor air decontamination. To do that the TiO2
powders were immobilized on borosilicate glass plates according to a dip
coating method. Then, the photocatalytic performance of these plates under
visible light was evaluated in a continuous gas flat plate photoreactor using
nitrogen oxide gas (NO) as the pollutant. The photocatalytic NOx
degradation by immobilized TiO2 powders was related with their
optical properties, finding a clear correlation between them.
These results are useful to decide which TiO2 will be more
efficient in a full scale air decontamination process under indoor conditions.
