Photocatalytic Degradation of Dyes in Water: Case Study of Indigo and of Indigo Carmine
TLDR
In this paper, a detailed degradation pathway has been determined by careful identification of intermediate products, in particular, carboxylic acids, whose decarboxylation by photo-Kolbe reactions constitutes the main source of CO2 evolution.About:
