Super stable POM nanostructures improve efficiency in electrocatalytic production of hydrogen
Published: 23 February 2024
High purity hydrogen gas has a great potential in future green energy solutions. Its major source is the electrochemical cleavage of water – a technology that is in itself energy demanding and challenged by side reactions in the oxygen evolution process at the anode. Efficient electrocatalysts permitting to facilitate anode reactions are therefore highly requested. The state-of-the-art materials are highly expensive, made of an oxide of a noble metal ruthenium.
A new study led by researchers of the Department of Molecular Science at SLU published in the American Chemical Society journal Inorganic Chemistry demonstrates that efficient (close to 100%) noble metal free electrocatalysts can be produced from nanostructures of smallest metal oxide (sand mineral) nanoparticles, so-called polyoxo-metalates (POMs).
