摘要 A Ni/Al layered double hydroxide(LDH) nanoparticle modified carbon ceramic electrode(Ni/Al LDH/NMCC) was fabricated and used for the electrocatalytic oxidation of methanol and ethanol in alkaline media.Cyclic voltammetric(CV) studies showed that it gave a significantly higher activity for methanol and ethanol oxidation and can be used as an electrocatalytic anode for fuel cells.The kinetic parameters of the electron transfer coefficient(α) and number of electrons involved in the rate determining step(nα) for the oxidation of methanol and ethanol were determined using CV.The anodic currents showed a linear dependence on the concentration of methanol and ethanol.
