Abstract

Ru nanodendrites composed of ultrathin fcc/hcp nanoblades were synthesized by a facile solvothermal reduction of Ru³⁺ together with Cu²⁺ followed by selective etching of Cu, resulting in a micro/mesoporous electrocatalyst that is highly efficient and stable for the hydrogen evolution reaction in alkaline media and outperformed commercial Pt/C at a lower cost.
