Seed-assisted synthesis of fcc Ru-Cu bimetallic nanostructures and their catalytic properties for the hydrogen evolution reaction
Adjusting the chemical composition and/or crystal structures is an important approach to tune the activity of catalysts. Herein, we reported a facile one-step synthesis procedure of Ru-Cu bimetallic nanostructures with the fcc phase, in which the growth of fcc-Ru was induced by the fcc-Cu seeds. By...
