The article presents the results of a study of the photocatalytic activity of coatings based on titanium dioxide on various structural elements of buildings. Fine-grained lightweight concrete, porcelain stoneware and window glass were used as a base. TiO2 coating was applied by reactive magnetron sputtering. The structure and phase composition of the coatings were investigated by scanning electron microscopy and X-ray phase analysis. The photocatalytic activity of the samples was evaluated according to ISO 27448: 2009 and ISO 10678: 2010. The photocatalytic efficiency of the obtained TiO2 coatings on building materials is shown. The data obtained allow us to make a preliminary assessment of the effectiveness of the application of this method of applying photocatalytic coatings to structural elements of buildings, which will be clarified in the course of future studies.
