Description	Thin films of TiO2 exhibiting developed mesoporosity with large surface area and pores ca 10nm in size were shown efficient photocatalyst in the decomposition of thin layers of oleic acid deposited on their surface. The pore walls of these films were composed of small anatase nanocrystals (ca 40-60%) and some amorphous phase. As major intermediates of the oleic acid decomposition, nonanal and 9-oxononanoic acid were identified. Azelaic and nonanoic acid were detected as well, representing minor intermediates. These compounds have been shown to correspond with the products of a simulated oxidative degradation of cis-3-hexenoic acid computed by means of quantum chemistry. Cis-3-hexenoic acid was chosen as a simplified model of oleic acid having similar but reduced structure. It enabled to perform the theoretical study with a reasonable consumption of computation time.
