SPEA11

Dr. Olivier Monfort attended the 11th European Conference on Solar Chemistry and Photocatalysis: Environmental Applications (SPEA11) in Turin, Italy where he gave a talk on our ongoing research on "Iron-based nano-photocatalysts: Coupling of photocatalysis and Fenton-based processes for caffeine degradation in water". You can find the detailed programme of the conference here and hereafter is the abstract of Dr. Monfort's contribution:

Iron-based nano-photocatalysts consisted of anodic TiO2 nanotube layers modified at their surface by Fe(III) which was deposited by spin-coating using different concentrations. The degradation of caffeine was performed under UVA at different pH in the presence of the nano-photocatalysts with and without H2O2. At pH = 3, photocatalysis was the predominant process without H2O2, and the Fenton-based reactions had a significant contribution in the presence of H2O2. In both systems, the contribution of photocatalytic and Fenton-based processes was determined, thus opening the doors in the development of photochemically versatile materials. In addition at pH = 7 which is a relevant pH for applications in wastewater treatment, ethylenediamine-N,N’-disuccinic acid (EDDS) and ascorbic acid, respectively, was added to increase the availability of iron species.
