The pore walls of these films were composed of small anatase nanocrystals and some amorphous phase. Nonanal and 9-oxononanoic acid were identified as major intermediates of the oleic acid decomposition, while azelaic and nonanoic acids represented minor ones. These compounds corresponded 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, which enabled to perform the theoretical study with a reasonable consumption of computation time. The simulated oxidative degradation of cis-3-hexenoic acid was induced by an attack of hydroxyl radical on the C=C double bond.
