氫能是目前極具發展性的能源，由於其應用廣泛，反應後的生成物較乾淨、低汙染且具再生性，是全球最受矚目的替代能源之一。鹼性陰離子交換膜燃料電池為其中一種應用，以非常高效率的方式將化學能轉化成電能以供使用。但由於其所使用的白金觸媒昂貴，造成無法普及化之問題，希望發展低價格並具高效能的非白金觸媒以降低貴金屬的用量，成為近年來研究之趨勢。
本研究合成奈米線狀的碲作為模板，接著讓奈米級的鈷金屬有機骨架（ZIF-67）沿著模板成長，在750 oC的熱處理後，觸媒具有最佳的氧氣還原活性且其電子轉移數可達3.99，已非常接近理想之電子轉移數。根據X光光電子能譜（XPS）之氮原子能譜結果顯示，此觸媒除了具有一定比例的Pyridinic-N及Graphitic-N外，Co-N化學鍵是此觸媒中提供活性點的關鍵，再經由X光吸收光譜（XAS）及延伸X光吸收細微結構（EXAFS）分析的結果，可確定鈷的化學鍵結種類及配位數，而利用高解析穿透式電子顯微鏡（HRTEM）影像得知，熱處理後仍維持線狀形貌，類似豌豆狀的觸媒結構中，內部含硫族化合物CoTe的鍵結，可對電化學活性有一定的貢獻，而外部的導電石墨層則可增加導電度。此外，觸媒以線性掃描伏安法（LSV）進行30000圈穩定性測試，觸媒之半波電位僅衰退16.0 mV，藉由特殊形貌維持觸媒的電化學表現。最後將最佳合成條件之觸媒應用於鹼性環境之全電池測試，其表現優異，與白金碳觸媒（Pt/C）相當，在非貴金屬觸媒中具有相當的競爭力。
此研究之新型材料有效保留其特殊形貌，且具有高效率催化活性，在未來應用在許多電化學反應和系統中，此一觸媒具有實際應用價值。

Hydrogen energy is a promising solution to develop sustainable and alternative energy throughout the world. The anion exchange membrane fuel cell (AEMFC) is one of the applications which is an electrochemical power source that transforms chemical energy into electricity efficiently. To decrease the usage of precious metal catalysts, the development of non-precious metal catalysts is the trend in recent years.
In this work, the Tellurium nanowire structure had been the template for the growth of nanoscale ZIF-67, due to its metallic feature can lead to better conductivity in electrochemical processes. After Nucleation, Nano-Z67/NwTe was the best catalyst treated at the optimized temperature, 750 oC. The XPS analysis showed the higher percentage of Co-N bonding, and the XAS fitting results confirmed the existence of Co-N and the formation of CoTe. Nano-Z67/NwTe-750 showed less decreasing of half-wave potential, and competitive performance of power density to Pt/C.
