Abstract

銅催化劑的產物選擇性取決於中間產物類型,從所有提出反應路徑中歸納為兩種主要反應:氫化反應與碳碳耦合反應,其中涉及到氫與一氧化碳溢出行為。然而,關於此兩種行為目前僅由理論計算討論,並無直接實驗證據支持。本計畫將設計多種以銅為主體之單原子轉合金催化劑,並將整合場效電晶體/電化學系統、活性氫原子產生器/電化學系統及臨場拉曼光譜來研究溢出行為,搭配臨場吸收光譜,釐清催化劑結構、溢出物種及物種濃度與產物選擇性之關係,藉由所得到的結果設計與調控異單原子合金催化劑,取得期望之還原產物。預期能在學術研究中有更深入的探討,於工業上能提供一開發高選擇性電催化劑之設計基礎,進而提升我國能源發展之地位。
