Unraveling how the crystal phase and dispersion of mesoporous carbon-confined Ru nanoclusters govern full-pH hydrogen evolution performance
Abstract
, respectively, at an overpotential of -50 mV. The excellent activity stems from (1) the pore confinement effect, which promotes the formation of ultrasmall Ru NCs (1.64 nm) and suppresses metal leaching; (2) the S doping, which modulates the electronic structure of Ru and reduces the water dissociation barrier; and (3) the hollow mesoporous architecture, which accelerates mass and electron transport. This work provides insights for designing high-efficiency pH-universal electrocatalysts.
