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