In order to improve the sensitivity and stability of material for detection hydrogen peroxide, Ni/N/MPC nanocomposites were synthesized by Ni-based biomass doped with nitrogen. Nickel atoms offer such advantages as good catalytic activity low cost, while nitrogen doping facilitates formation stable hybrid structures abundant functional groups on surface nanocomposites. The linear equation characterizing electrode response from was derived relationship between current signal I H 2 O concentration, demonstrating a range 0.05–240.15 mmol l −1 , along limit 0.84 μmol (S/N = 3). contrast, electrochemical signals Ni/NGCE Ni/N/GCE sensors significantly lower than those obtained composite materials during cyclic voltammetry testing. practical sample analysis, recovery rate RSD in tap water samples 97.2%–98.6% 5.5%–6.4%, respectively. Ni/N/MPC/GCE sensing platform presents excellent enhanced sensitivity.
