NiFe₂O₄ Nanoparticles as Highly Sensitive Electrochemical Sensor for Nitrite Determination

Applied Organometallic Chemistry, Год журнала: 2025, Номер 39(4)

Опубликована: Март 24, 2025

ABSTRACT Taking into account the harmful influence of superfluous nitrite content onto ecosystem and human health, sensitive real‐time estimation its concentration by developing reduced cost efficient catalytic surfaces seems as a vital problem to be solved. Herein, sensing platform for ions in water samples was designated based on mixed transition metal oxides. NiFe 2 O 4 nanoparticles were fabricated using simple straightforward sol–gel protocol followed calcination at 900°C. Convenient physical characterization tools employed investigate crystal structure, morphological, chemical composition, elemental mapping distribution this formed nanocomposite. The cubic spinel structure confirmed XRD TEM analyses. average crystallite size estimated 25.70 nm wide particle range between 10 50 nm. Cyclic voltammetric study revealed pronounced oxidation current density nanomaterial when contrasted that Fe 3 1.283 times. altering scan rate electrolyte pH during relevant electrochemical measurements electroactivity oxide nanostructure evaluated. Some kinetic parameters reaction nanocomposite including Tafel slope (59.96 mV dec −1 ), exchange (2.13 × −7 A cm −2 diffusion coefficient (1.178 −3 s electron transfer constant (2.074 ) values. linear towards with outstanding sensitivity 70.57 nA μM lowered detection limit 23.9 nM could monitored nanopowder. These encouraging results might focus further efforts synthesizing binary oxides surprising activity numerous analytes determination.
