Gao & Kanji 62 reported contradictory results. Additionally, a study on inorganic mineral dusts (Arizona test dust and kaolinite) has revealed an enhancement in ice nucleation ability after exposure to O3. We employed FTIR and SEM measurements to track chemical and morphological alterations due to exposure to O3 and photooxidation. FTIR spectra with peak assignments, and SEM images for all samples before and after oxidation experiments are provided in the Supplement Information for comparison purposes.
