Porous confinement: Stable and full exposure of Ru nanoparticles towards efficient electrocatalytic hydrogen evolution

Abstract

Porous-confined Ru nanoparticles with full accessibility and structural stability are prepared via an in situ pyrolytic etching strategy. The in situ-formed porous-confined structure endows the catalyst with excellent electrocatalytic hydrogen evolution activity and stability, which offers a valuable reference for the design of efficient metal nanocatalysts.
