Abstract
Abstract Single‐atom catalysts (SACs) show great promise for electrocatalytic water splitting due to their exceptional metal atom utilization efficiency. Herein, it is demonstrated that Ru single atoms (SAs) anchored on Co 3 O 4 nanorod arrays (Ru x ‐Co 3 O 4 , where x is the Ru loading in weight percent) afford outstanding electrocatalytic performance and durability for the oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and overall water splitting across a wide pH range (0.3–14). Ru 8% ‐Co 3 O 4 achieves 10 mA cm⁻ 2 at overpotentials of only 214, 286, and 138 mV for OER, and 13, 72, and 59 mV for HER, in 1 m KOH, 0.1 m PBS, and 0.5 m H 2 SO 4 , respectively, outperforming benchmark RuO 2…
