Radiation-Induced Synthesis of High-Entropy Alloys: Novel Catalytic Solutions for Hydrogen Economy

RadHydroCats brings radiolytic synthesis, materials science and electrochemistry together to explore catalysts for water electrolysis—with the aim of reducing reliance on scarce precious metals.

Our aims and approach
01 /

Radiolytic synthesis

Exploring gamma irradiation as a route to alloy nanoparticles at room temperature and atmospheric pressure.

02 /

Multi-element design

Bringing experiment and theory together to understand composition, structure and potential catalytic sites.

03 /

Hydrogen & oxygen evolution

Investigating electrocatalysts for the two half-reactions of water electrolysis.
