Electrocatalytic water splitting plays a vital role in the hydrogen fuel industry, but suffers from the lack of efficient non-platinum (Pt) hydrogen evolution reaction (HER) catalysts. Metallic Ru has proven to be one of the promising candidates for the HER. However, the syntheses of Ru nanoparticle...
