中文摘要 | 本文主要是研究氫硼化鈉還原劑的濃度與白金沈積量,在以 Takenata-Torikai 法 製備白金/Nafion電極用於氧氣感測中,對電極活性面積及靈敏度之影響。以0,06N氫硼化鈉 製備之白金/Nafion電極,其靈敏度隨著白金沈積量之增加(由2.59增加至7.76mg/cm2),而呈 非線性之增加(由0.0242增加至0.106μA/cm2ppm)。然而,在白金沈積量為5.20mg/cm2時, 每單位白金沈積量之靈敏度為一最大值。氣體感測之模式亦同時提出,以說明氣體感測之現 象。 |
英文摘要 | The influences of the reductant concentration of NaBH4 and the quantity of Pt loading on the active surface area and the sensitivity of the Pt/Nafion electrodes prepared by a Takenata-Torikai method in detecting oxygen were investigated in this study. The sensitivities of Pt/Nafion electrodes prepared in 0.06 N NaBH4 increase non-linearly from 0.0242 to 0.106μA/cm2 ppm with increasing Pt loadings from 2.59 to 7.76 mg/cm2. However, The sensitivities per unit Pt loading show a maximum at Pt loading of 5.20 mg/cm2. A sensing model was also proposed to illustrate the sensing phenomenon. |
