Ni-O-C/LNSP Core-Shell Heterostructure Mimicking Noble Metal-like Activity and Nonenzymatic Electrochemical Lactate Regulation in Human Sweat.

Herein, a core/shell LNSP (lamellar nanosheet-nanoplate) of nickel oxy carbide (Ni-O-C/LNSP) has been synthesized by a solvent-devoid combustion process, which exhibits exceptional oxygen evolution efficiency (OER) performance with an overpotential of 311 mV, a Tafel slope of 116 mV dec, and stability over 8 h with 2.8% potential loss owing to more exposed active sites and high conductivity with the interface effect. The activation energy of 28 kJ/mol was calculated for electrolysis using Ni-O-C/LNSP.
