Abstract 1H NMR is a common technique for tracking chemical reactions; here it is demonstrated that it can be used effectively to evaluate efficiency of photocatalysts. The photocatalytic degradation of acetylsalicylic acid (Aspirin) by P25 TiO2 and its photolytic degradation by UV light were examined; and they were found to be comparable, suggesting that this breakdown reaction does not benefit greatly from the catalyst’s presence. Due to its chemical specificity, 1H NMR enables identification of breakdown products, which is a useful consideration in wastewater treatment and mechanistic studies.
