Low-loaded Ru on Hollow SnO for Enhanced Electrocatalytic Hydrogen Evolution

In response to the challenges of intermediate poisoning and the high cost of noble metal catalysts in the hydrogen evolution reaction (HER), we develop a Ru-doped SnO catalyst. This Ru-SnO catalyst has the characteristics of low Ru loading and a hollow structure, which endow it with good electrocatalytic activity and stability for the HER.
