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.

由超薄的fcc / hcp纳米刀片组成的Ru纳米树枝晶，用于碱性溶液中的氢释放反应†

通过将Ru ³⁺与Cu ²⁺一起进行溶剂热还原，然后选择性刻蚀Cu，可合成出由超薄fcc / hcp纳米叶片组成的Ru纳米树枝晶，从而产生了对氢气析出反应高效且稳定的微/介孔电催化剂。可以在碱性介质中以更低的成本胜过市售的Pt / C。
