The influences of the reductant concentration of NaBH4 and the quantity of Pd loading on the active surface area and the sensitivity of the Pd/Nafton electrodes prepared by an impregnation-reduction method in detecting oxygen were investigated in this study. The Pd/Nafion electrodes with Pd loading of 6.90 mg cm-2 obtained at 0.006 MPd(NH3)4Cl2 and 0.06 MNaBH4 show maximum sensitivities of 0.0198 μA ppm-1 and 0.0280 μA ppm-1 obtained in O2 concentration regions of 0∼5000 and 5000∼50000ppm, respectively. A sensing model was also proposed to illustrate the sensing phenomenon.
