The homemade, porous carbon material, thermolysis prepared from Novolac phenol‐formaldehyde resin, in situ modified with Co 3 O 4 nanoparticles and mixed with single‐wall carbon nanotubes, was used in selective sensing of prominent antioxidant α‐lipoic acid (LA). XRD, SEM and EIS measurements were used for characterization of material composition, structure, morphology and improved conductivity. The quantification of LA at TPCo 3 O 4 &SWCNTCPE was done by a square‐wave voltammetric technique in BR buffer solution at pH 6. The linear working range was recorded from 2 to 100 μM of LA and the proposed electrode material was successfully applied in the determination of LA in dietary supplements.
