Research

Electrochemical water splitting into oxygen and hydrogen is one of the most promising routes for renewable energy conversion and storage, but at a large scale requires developing of precious metal free catalysts. The bottleneck of water splitting is the inefficiency of low cost catalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The recent demonstration that oxides of iron group metals (oxides based on Co, Ni and Fe and their alloys) have interesting electrocatalytic properties towards water decomposition into oxygen via the OER is opening interesting perspectives in terms of applications.

My research interest consists in the synthesis and characterization of transition metal oxide model catalysts for water splitting. The oxides based on Co, Fe and their alloys are prepared by direct electrodeposition at high temperature of a ultrathin epitaxial film on a gold single crystal.

The characterization of the films includes the study of the morphology (SEM, AFM), structure (XRD) and electrochemical measurements to study their catalytic activity. At synchrotron facilities, it will be possible to study their structure while the catalyst is working (operando XRD).
