Resumen:
This document specifies a method for the determination of photocatalytic activity of surfaces by degradation of methylene blue using artificial illumination and characterizes the ability of photoactive surfaces to degrade dissolved organic molecules on ultraviolet illumination. This method specified is not applicable to characterizing the photoactivity of surfaces on visible illumination. A correlation of the photocatalytic activity with respect to cleaning from direct contamination, degradation of gaseous molecules in the ambient air or antimicrobial efficacy can exist, especially for surfaces with low photonic efficiency.
