Figure 5: (a) Effect of applied potential on the current response of the Mg-MCM-41/PVA/Lac/Au electrode to 0.05 mM catechol in pH 4.8 acetate buffer solution. (b) Effect of pH of acetate buffer solution on the current response of the Mg-MCM-41/PVA/Lac/Au electrode to 0.05 mM catechol at 0.45 V (versus SCE). (c) Effect of temperature on the current response of the Mg-MCM-41/PVA/Lac/Au electrode to 0.05 mM catechol in pH 4.8 acetate buffer solution at 0.45 V (versus SCE).
