Understanding the Hidden Electrical Barrier at Solid¨CLiquid Interfaces
- Press realease
Hydrogen is at the heart of the transition to carbon neutrality, serving as both an energy carrier and a reactant for green chemistry, and even a pathway to convert CO? into fuel. However, the large-scale production via electrolysis requires catalysts that are much more economical and efficient than those currently available. Just like many of the world¡¯s most critical energy technologies, such as next-generation batteries, hydrogen production depends on a single, invisible boundary: the place where a solid electrode meets a liquid. While this interface is the heart of the energy transition, it has remained notoriously difficult to describe, limiting our ability to design truly efficient and affordable materials. In the study "The role of the Helmholtz potential on electrocatalytic activity" published in Nature Communications, Ars¨¨ne Chemin and colleagues from the Institut Lumi¨¨re Mati¨¨re (Lyon 1 Universit¨¦ Claude Bernard / CNRS) and the Helmholtz-Zentrum Berlin have introduced a new theoretical framework connecting charge behaviour in solids and liquids, and demonstrate its implications for the production of hydrogen from water.

_ Structuring Projects
_The University¡¯s structuring projects are part of its academic strategy and its values of diversity, agility, solidarity, and responsibility. These transformative projects, aligned with the government¡¯s priorities, strengthen its world-class missions in education, research, and innovation, and enable the development of infrastructure and services that meet international standards.
_
_They thus shape a university that is ever more deeply rooted in its local community and resolutely focused on the future. Through these diverse projects, Claude Bernard Lyon 1 University, together with its many partners, tackles the complex challenges of our society¡ªsuch as digital transformation, inclusion, the environment, artificial intelligence, and health¡ªusing a multidisciplinary approach.
_
_These scientific projects confirm the University¡¯s leading role in advanced research excellence and scientific innovation, and affirm its position as a committed advocate for a more sustainable world.
