Carbon based materials: Apromising approach for water depollution by electrochemical advanced
oxidation processes

S
carcity of pure water worldwide is dramatically affecting the economic development ofThirdCountries but also the industrial
growth of others. Towards the water recycling and reuse, Electrochemical Advanced Oxidation Processes (EAOPs) are of
high interest since they are very efficient in the degradation of refractory pollutants that cannot be eliminated by conventional
techniques. Amongst them, the electro-Fenton (EF) process allows the in situ generation of highly reactive and nonselective
hydroxyl radicals indirectly by cathodic oxygen reduction, its subsequent H

from the reduction of
dissolved oxygen but it suffers from drawbacks like relatively low electronic conductivity and electrochemical active surface
area. With the aim to increase carbon felt efficiency toward the electro-Fenton process, we develop in our research team,
different modification routes to get microporous reactive carbon-based structures. It deals from basic thermal treatment under
controlled atmosphere to microporous carboneous coating prepared by combining Atomic Layer Deposition and solvothermal
MOF growth on carbon felt, going through graphene functionalization and LDH deposition for heterogeneous catalysis. We
will discuss synthesis, characterization and electro-catalytic properties of the different structures. Carbon based materials will
be then integrated in an electrolysis system for water treatment but also in a prospective fuel cell–Fenton system for zero-
energy water depollution. Efficiency will be shown through the degradation and mineralization of pharmaceutical residues
and organic dyes.
Biography
Marc Cretin has received his PhD degree in Electrochemistry (National Polytechnic Institute of Grenoble France) in 1996, and joined Geneva University to develop
electrochemical sensors for biomedical and environmental analysis. In 1998, he gained a position of Assistant Professor (ENSCM/Montpellier/France) to work
on membranes materials for detection, separation and reaction. He’s full Professor since 2012 at the University of Montpellier and works mainly in the field of
materials for energy and environment. He focuses his research mainly on electroactive materials for fuel cells, biofuel cells, EAOP (electrochemical advanced
oxidation processes) and ceramic membranes for water treatment. He is currently the Director of the Department of Physico-Chemistry, Interface and Polymer
at the European Membrane Institute of Montpellier (IEM) and Co-Director of the International French-Russia Laboratory MEIPA Ion Exchange Membranes and
Associated Processes. Up to March 2017, he has co-authored more than 80 peer reviewed papers.
