Abstract Urea oxidation reaction (UOR) has garnered significant attention in recent years as a promising and sustainable clean‐energy technology. Urea‐containing wastewater poses severe threats to the environment human health. Numerous studies hence focus on developing UOR viable process for simultaneously remediating converting it into energy. Moreover, UOR, which thermodynamic potential of 0.37 V (vs reversible hydrogen electrode, RHE), shows great promise replacing energy‐intensive oxygen evolution (OER; 1.23 vs RHE). The versatility stability urea, particularly at ambient temperatures, make an attractive alternative fuel cells. Since entails complex intermediate adsorption/desorption process, many are devoted designing cost‐effective efficient catalysts. Notably, transition metal‐based materials with regulated d orbitals have demonstrated process. However, comprehensive reviews focusing catalysts remain scarce.

Abstract Water‐splitting reactions such as the hydrogen evolution reaction (HER) and oxygen (OER) typically require expensive noble metal‐based electrocatalysts. This has motivated researchers to develop novel, cost‐effective electrocatalytic systems. In this study, a new multicomponent nanocomposite was assembled by combining functionalized multiwalled carbon nanotubes, Cu‐based metal–organic framework (MOF) (HKUST‐1 or HK), sulfidized NiMn‐layered double hydroxide (NiMn‐S). The resulting nanocomposite, abbreviated MW/HK/NiMn‐S, features unique architecture, high porosity, numerous electroactive Cu/Ni/Mn sites, fast charge transfer, excellent structural stability, conductivity. At current density of 10 mA cm −2 , dual‐function electrocatalyst shows remarkable performance, with ultralow overpotential values 163 mV 73 (HER), well low Tafel slopes (57 75 dec −1 respectively). Additionally, its turnover frequency (4.43 s for OER; 3.96 HER) are significantly superior those standard Pt/C IrO 2 synergistic effect nanocomposite's different components is responsible enhanced performance. A functional theory study revealed that multi‐interface heterostructure contribute increased electrical conductivity decreased energy barrier, in HER/OER activity. presents novel vision designing advanced electrocatalysts performance water splitting.

The emerging lattice-oxygen oxidation mechanism (LOM) presents attractive opportunities for breaking the scaling relationship to boost oxygen evolution reaction (OER) with direct OLattice-*O interaction. However, currently LOM-triggering rationales are still debated, and a streamlined physicochemical paradigm is extremely desirable design of LOM-defined OER catalysts. Herein, Ni metal-organic framework/black phosphorene (NiMOF/BP) heterostructure theoretically profiled constructed as catalytic platform LOM-derived studies. It found that p-type BP host can enlarge Ni-O bond polarizability NiMOF through stretching valence declining synergically. Such an enlarged will in principle alleviate lattice confinement benefit LOM pathway performance. As result, optimized NiMOF/BP catalyst exhibits promising performance low overpotential 260 mV at 10 mA cm-2 long-term stability 1 M KOH electrolyte. Both experiment calculation results suggest activated more balanced step barrier catalyst. This research puts forward criterion LOM-scaled electrocatalysts water oxidation.
