A rapid, semi-quantitative, inexpensive method, using a simple digital scanner and an indicator ink, suitable for use in the laboratory, or in the field, for assessing the photocatalytic activity of commercial photocatalytic self-cleaning materials, such as glass, is described. The repeatability of the current method is found to be high and better than many of the previously reported ISO photocatalyst tests.
