Abstract
RuO<sub>2</sub>–NiO/NF, obtained through a dip-heating method, achieved continuous electrolysis for 2000 h at an ultrahigh current density. The RuO<sub>2</sub>–NiO interface promoted H<sub>2</sub>O dissociation and modulated chemisorbed O-containing intermediates, improving HER and OER activity.
