New Experimental Approach to Measure the Photocatalytic Activity of the TiO2 Nanosamples
Titanium dioxide (TiO2) samples are important industrial nano-objects with wide applications. For example nowadays TiO2 is the most abundantly used white pigment. The pigment is still in use, both in the production of contemporary art and for the conservation of older artwork as a retouching pigment. But next to its positive characteristics, the pigment has a major potential drawback: its photo-catalytic activity that can cause degradation of artworks in which it is used. So it is important to create methods to test the photo-catalytic activity of different quality of titanium dioxide samples. In this paper a new experimental set-up to measure the photo-catalytic activity of TiO2 samples is described.
