Herein, a core/shell LNSP (lamellar nanosheet–nanoplate) of nickel oxy carbide (Ni–O–C/LNSP) has been synthesized by solvent-devoid combustion process, which exhibits exceptional oxygen evolution efficiency (OER) performance with an overpotential 311 mV, Tafel slope 116 mV dec–1, and stability over 8 h 2.8% potential loss owing to more exposed active sites high conductivity the interface effect. The activation energy 28 kJ/mol was calculated for electrolysis using Ni–O–C/LNSP. integrated area 3.70 × 10–5 AV established MOOH* formation 4.619 10–16. ultrastability Ni–O–C/LNSP commercial application shown durability at 10/100 mA cm–2 OER (GC─8 h, 2.8%; NF─100 3.4/4.9%), UOR (60 3.4%), SWO 4.1%), MSWO 5.6%), overall water splitting (100 3.9%). effect pH addition tetramethylammonium cations (TMA+) reveals follows lattice mechanism. solar-driven 1.58 V shows effectiveness STH conversion. multiple applications projected as auspicious catalyst applications. Using Ni–O–C/LNSP, we have generated H2 effectively lower power consumption 771.08 LH2 kW h–1 than bare NiO (801 h–1). as-prepared used nonenzymatic lactate detection showed sensitivity 71.05 μA mM–1 1.54 [lactate] difference in human sweat corroborated under both anaerobic aerobic exercise conditions
