Chemist synthesizes gold-based electrocatalysts


Credit: RUDN University

A RUDN chemist has synthesized an electrocatalyst based on gold nanoparticles with organic ligands that can trigger both hydrogen production reactions and oxygen reduction reactions in fuel cells. The yield of products with the new catalyst was twice as high as when using a traditional platinum-based catalyst. The article was published in Journal of Materials Chemistry A.

Catalysts based on metal nanoparticles, for example, gold or platinum, are needed for reactions in fuel cells and in the industrial production of hydrogen. If organic molecules, ligands, are attached to nanoparticles, the activity of the catalyst can be increased. However, there have been few papers that investigate the capabilities of such catalysts so far.
Rafael Luque, a RUDN chemist, synthesized a catalyst based on gold nanoparticles stabilized with citrate, a salt of citric…
