Abstract

The mechanisms of the heterogeneous photocatalytic behavior of TiO2 and Cs3PW12O40 for the oxidative destruction of N-methylpyrrolidinone (NMP) in water are discussed. Both photocatalysts generate N-methylsuccinimide (NMS) and succinimide as the main intermediates from oxidation at the α-carbon and methyl positions. 2-Pyrrolidinone (2P) and 5-hydroxy-N-methylpyrrolidinone (5-HNMP) have also been identified as primary ...
