Highly dispersed ruthenium nanoparticles on nitrogen doped carbon toward efficient hydrogen evolution in both alkaline and acidic electrolytes

Abstract

Ultrafine ruthenium nanoparticles on nitrogen doped carbon show exceptional activity toward the hydrogen evolution reaction in alkaline and acidic electrolytes.

Enhancing the Hydrogen Evolution Performance of Tungsten Diphosphide on Carbon Fiber through Ruthenium Modification

“…Furthermore, distinct crystalline arrangements (highlighted in a white dotted-line) exhibit a lattice spacing of 0.21 nm in an inset, suggesting (002) Ru lattice planes. 52 The application of Fourier transform treatment to the HRTEM image revealed reflections corresponding to the atomic planes (101), (100), and (002) for the hexagonal Ru structure (Figure S6). These planes also align with those recorded in the XRD pattern of ∼4.8 mM Ru/WP 2 (Figure S5).…”

“…This lattice distortion in WP 2 could be due to the formation of a hydroxide group on the surface during the hydrothermal process. , The later discussion on XPS results will subsequently reveal the presence of the hydroxide group on the surface of Ru/WP 2 .
