abstract = {Electrochemical urea splitting provides a sustainable and
environmentally benign route for facilitating energy
conversion. Nonetheless, the sustained efficiency of urea
splitting is impeded by a scarcity of active sites during
extended operational periods. Herein, an atomic
heterostructure engineering strategy is proposed to promote
the generation of active species via synthesizing unique
Ru–O$_4$ coordinated single atom catalysts anchored on Ni
hydroxide (Ru$_1$–Ni(OH)$_2$), with ultralow Ru loading
mass of 40.6 μg cm$^{−2}$ on the nickel foam for
commercial feasibility. Leveraging in situ spectroscopic
characterizations, the structure-performance relationship in
low and high urea concentrations was investigated and
exhibited extensive universality. The boosted generation of
dynamic Ni$^{3+}$ active sites ensures outstanding activity
and prominent long-term durability tests in various
practical scenarios, including 100 h Zn–urea–air battery
operation, 100 h alkaline urine electrolysis, and over 400 h
stable hydrogen production in membrane electrode assembly
(MEA) system under industrial-level current density.},
