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.
