Methanol content in adulterated alcoholic beverages and gasoline recently has emerged as a common issue in many developing countries. Here we aimed to fabricate a novel sensitive and selective methanol sensor based on NiOOH/PANI-Gr and NiOOH/ PANI-CNTs interfaces. The results revealed that both sensing interfaces exhibited noteworthy electrocatalytic performance, high reproducibility towards methanol oxidation with a wide linear range of 0.5-500 mM, and a low detection limit of 0.290 mM. The fabricated interfaces were also highly selective towards methanol oxidation without any interferent signal from other alcohols, indicating the auspicious methanol sensors for the field-tests in controlling adulterated products (alcohol beverages and gasoline).
