本研究透過控制含有鈷以及硒之前驅物比例，再搭配界面活性劑與溶劑的使用，經水熱法處理後可得一特殊形貌之二硒化鈷。而利用此實驗流程，加入適當比例之碳材及尿素後，再使用化學氣相沉積儀燒結至特定溫度，即可製備出最佳條件之觸媒(CoSe2/NC)。經電化學量測後得知，該觸媒具有最佳之氧氣還原活性且其電子轉移數可達3.994，非常接近理想之電子轉移數4.0。另外，觸媒在經過線性掃描法(Linear Sweep Voltammetry)方式30000圈穩定性測試後，其半波電位衰退率僅5.9%，可知此觸媒在反應的過程中具備極佳之穩定性。同時也在鹼性陰離子交換膜燃料電池(Anion Alkaline Exchange Membrane Fuel Cell)測試中，達到146.3 mW cm-2 的高輸出功率。
此具有高催化活性及穩定性的觸媒可歸因於兩個因素，首先從氮的近邊X射線吸收細微結構(Near Edge X-Ray Absorption Fine Structure)圖譜中得知，有一特徵峰顯現為Co-N鍵結在鍵結能396.3eV的位置。因為氮原子本身具有的高電負度與二價鈷提供的空軌域，有效地促進電子轉移，進而增加活性。再者，硒氰酸根(SeCN-)的結構也因為其具有較高的氧化電位，因此可提升氧氣還原反應進行的效率。
利用此簡易的方法製備出具有獨特形貌之新穎高效率電催化觸媒，相信應用在其他電化學反應或系統中，也是極具發展潛力的選擇。

Cobalt diselenide is used to synthesize a transition metal with an active center that is supported by nitrogen-doped carbon materials—CoSe2/NC. CoSe2/NC demonstrates an excellent oxygen reduction reaction (ORR) ability with an electron-transfer number of 3.994, which is approximately equal to the ideal electron-transfer number 4.0. In an electrochemical measurement, CoSe2/NC presents excellent durability after 30,000 cycles linear sweep voltammetry (LSV) scan. When an anion (alkaline) exchange membrane fuel cell uses CoSe2/NC, superior performance is achieved in terms of the current generation. Moreover, a maximum power density of 146.3 mW cm−2 is obtained when a Fumapem® FAA-3 membrane is used.
The high catalytic performance of CoSe2/NC is due to two reasons—1) presence of selenocyanate (SeCN−) bonding in CoSe2/NC that promotes electron transfer and 2) presence of Co-N structures that act as active sites in an ORR. These characteristics of CoSe2/NC enhance the performance of the active sites and increase the kinetic reaction rate during the ORR, thus causing CoSe2/NC to be a promising catalyst.
