A. Mills et al., EFFECT OF PH ON THE STABILITY OF TIO2 COATINGS ON GLASS PHOTOCATALYSIS REACTORS FOR WATER-PURIFICATION, Journal of the Chemical Society, Chemical Communications, (23), 1994, pp. 2677-2678
TiO2 coated glass shows excellent stability in the range pH 2-9, howev
er, there is rapid and complete stripping of the TiO2 coating between
pH 11 and 12.
