Özet

Direct glucose fuel cells, essentially produce electricity from glucose, offer several advantage and might be employed in a range of applications. Becuase of stability and non-volatile, Glucose have high-intensity density. When it is oxidized water and CO2 are formed. In the current investigation, designed and synthesized new organic anode catalyst by using Thymol derivatives. Thymol based new hybrid molecules (G1,G2, and G3) were synthesized via Sonogashira cross coupling and condensation reactions. Then, electrochemical activities and charge transfer resistances (Rct) of all prepared thymol-based catalysts were studied via cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), respectively in 0.5 M glucose alkaline solution. Thymol based organic catalysts exhibited a good current density at around 0.1 mA.cm(-2) for the 2-isopropyl-5-methylphenyl 4-oxo-4-(5-(p-tolylethynyl)thiophen-2-yl)butanoate (G3). As a result, A new generation of ecologically friendly and alternative metal catalyst for direct glucose fuel cells is thymol derivatives-based catalyst..
