Better green hydrogen production with new material combination

June 23, 2024 – The chemical reaction for producing hydrogen from water becomes significantly more efficient when a combination of new materials is used in three layers – at least, that’s what researchers at Linköping University claim.

They are developing materials that enable the production of hydrogen (H2) from water (H2O) using solar energy.

Hydrogen from water is a promising renewable energy source, especially when produced using sunlight.

When sunlight hits the material, it generates electric charges that are used to split water molecules. A major challenge in developing such materials is preventing the positive and negative charges from recombining and neutralizing each other.

In their study, the researchers show that by combining a layer of cubic silicon carbide with two other layers, the material – Ni(OH)2/Co3O4/3C-SiC – can better separate these charges, resulting in more efficient water splitting.

The research was published earlier this year in ACS under the title ‘Manipulating Electron Structure through Dual-Interface Engineering of 3C-SiC Photoanode for Enhanced Solar Water Splitting.”
