Amethod for the decomposition of ionic liquid (ILs) by photocatalysis has been demonstrated. The participation of ILs in light absorption by TiO2 was shown. The IL molar mass influence on photocatalytic decomposition was proven. The samples with a lower molarmass had higher stability under UVlight in the presence of TiO2. The degree of decomposition depends upon the cation and anion. The easiest to degrade proved to be ILs with a long alkyl substituent. Ammonium ILs (choline derivatives) with hydroxyl group proved to bemore stable than with acetyl group. Themost readily decomposable salts are phosphonium ionic liquids.
