Corrosion inhibitors
Fe → Fe2+ + 2e−
In pickling acid, steel dissolves and its electrons reduce protons to hydrogen. Organic inhibitors adsorb on the surface and slow both reactions.
Ph.D. in Physical Chemistry. IDI laboratory, ENSCK, Ibn Tofaïl University, Kénitra.
My research covers materials protection, metal air batteries and green hydrogen in strongly acidic and alkaline media, combining electrochemistry, surface analysis and computational chemistry.

53 publications, 611 citations and an h-index of 15 on Scopus (October 2026). Two patents filed with OMPIC, and 88 peer reviews for 23 journals.
The three topics share one reaction. Hydrogen evolution is a side reaction in a pickling bath, a loss in an Al-air battery and the product of an electrolyser.
Fe → Fe2+ + 2e−
In pickling acid, steel dissolves and its electrons reduce protons to hydrogen. Organic inhibitors adsorb on the surface and slow both reactions.
Al + 4OH− → Al(OH)4− + 3e−
In an Al-air battery the aluminium should dissolve, but its electrons belong in the external circuit, not in hydrogen at its own surface. Electrolyte additives suppress that self-corrosion.
2H2O + 2e− → H2 + 2OH−
In an electrolyser, hydrogen is the product. Electrode materials, operating conditions and the power supply decide what each kilogram costs.
Open to collaborations and new projects.
