Amorphous Y(OH)3-promoted Ru/Y(OH)3 nanohybrids with high durability for electrocatalytic hydrogen evolution in alkaline media

A novel Ru/Y(OH)3 nanohybrid with high activity and excellent durability for electrocatalytic hydrogen evolution in alkaline media was developed. The enhanced performance mainly arose from the amorphous Y(OH)3 scaffold that both facilitates water dissociation and enhances the structural stability of Ru/Y(OH)3 due to the strong interaction between Ru and Y(OH)3.
