This study describes the synthesis of a phenyl trisilanol polyhedral oligosilsesquioxane (POSS) employing calcium and its subsequent modification by phosphate methylene blue for electrochemical applications. Fourier transform infrared spectroscopy, X‐ray photoelectron energy‐dispersive scanning electron microscopy, were employed to characterize developed material. The obtained POSS was characterized cyclic coltammetry graphite paste electrode, exhibiting well‐defined redox pairs. modified electrode demonstrated an adequate electrocatalytic response pyridoxine. Regarding catalytic pyridoxine electro‐oxidation, exhibited linear ranging from 7.0 × 10 − 6 1.0 ³ mol L 1 , with limit detection 3.24 . studied material, therefore, comprises potential candidate development sensors detection.
