    Abstract: 本計晝的目標為開發鉑-二氧化鈦/碳黑(Pt-TiO2/C)複合奈米顆粒電催化劑的新 製程,並對所電催化劑之效能進行評估與最佳化。本研究計晝使用經NaOH修飾過之 碳黑,製備Type A與Type B兩種具有不同大小Ti〇2奈米顆粒之Pt-Ti〇2/C電催化 劑,對於電催化劑之組成結構、電催化曱醇氧化反應(methanol oxidation reaction, MOR) 效能以及抵抗一氧化碳毒化之能力進行量測與分析,並以(1)提高電催化劑抵抗一氧化 碳毒化之能力;(2)提高電催化MOR效能為研究進行之主要目標。此外,本就計晝也將 研究於紫外光的照射下,Pt-TiO2/C對於MOR的催化效能是否可因TiO2之光催化特 性而被提升。
    The major goal of this research is to develop a new synthesis procedure for the preparation of effective Pt-Ti〇2/C nanocomposite electrocatalysts for methanol oxidation reaction (MOR). Type A and Type B of Pt-Ti〇2/C electrocatalysts with different TiO2 nanoparticle sizes will be prepared, and NaOH modified carbon black will be employed as the support for the Pt and TiO2 nanoparticles. The nanoparticle structures, compositions, MOR efficiencies and the CO tolerance abilities of the electrocatalysts will be investigated, and attempts will be made to improve the performances of the electrocatalysts. Moreover, the MOR efficiency of the Pt-TiO2/C under the irradiation of UV light will also be studied to determine that whether the photocatalysis ability of the TiO2 can enhance the MOR efficiency or not.
