A sacrificial template, Fe-MIL-88 is used to synthesize Ni–Fe layered double hydroxide (Ni–FeLDH). The metal-organic framework (Fe-MIL-88) is synthesized from the precursors, ferric nitrate and terephthalic acid. Electrocatalytic oxidation of kojic acid (KA) is realized by Ni–Fe LDH film which is coated on a glassy carbon electrode (GC). Under the optimized conditions, amperometry measurements at the Ni–Fe LDH coated GC as a function of KA concentration demonstrates a sensitive determination of KA. The calibration curve shows two linear ranges, 1–1500 lM and 1500–4500 lM for the KA determination.Detection limit for the KA determination is estimated as 0.73 lM. The practical applicability of this method is confirmed by measuring the KA concentration present in various real samples.
