Main project: Nanostructured porous nickel electrodes for photo-electrochemical hydrogen production
Funding: Research assistant (UCL)
Supervisor(s): Joris Proost

Adeline obtained her master in Chemical and Materials Engineering at Université catholique de Louvain (Belgium) in 2014. Since then, she is working under the supervision of Prof. Joris Proost on the hydrogen production by water electrolysis with the view to replace actual energy sources by cleaner ones. The goal of her research consists in improving the electrochemical cell efficiency by tailoring nickel electrodes in order to favor gas bubble detachment and then reduce the overpotential due to mass transport. This is done by depositing Al-Ni alloys by magnetron co-sputtering, and then by chemically treating these alloys in a concentrated hydroxide solution with the aim of leaching out the Al. Another aspect of her research focus on the hydrogen absorption by nickel electrode during hydrogen evolution reaction. It consists in studying the hydriding mechanisms of Ni thin film electrodes into aqueous medium as well as characterize their internal stresses and microstructure effects as a function of their processing conditions since they influence kinetics and thermodynamics of hydriding.
