本實驗以不鏽鋼基板 (SUS304)為基底，並在其上成長奈米碳管陣列，而後利用熱化學氣相沉積的方式合成出二硫化鉬，並將其披覆於奈米碳管陣列上，將之作為電雙層電容器之電極材料。奈米碳管本身不僅具有高導電性、高化學穩定性以及高比表面積等特性，且本實驗透過黃光微影技術定義出奈米碳管的生長區域，將奈米碳管陣列以蜂巢狀的樣貌呈現，可以進一步增加電極與電介質電解液之接觸面積，以增加電化學電容特性的展現。二維的過渡金屬二硫化物 (transition metal dichalcogenides, TMDs)本身之層狀結構可以提升電化學量測中的有效反應面積，並同時減少電子轉移和離子擴散之路徑，從而提升電極材料之功率性能，其中，二硫化鉬由於本身優異的電化學活性和理論電容值，使得二硫化鉬時常被拿來用用在電化學相關之實驗中。本實驗複合二硫化鉬與蜂巢狀奈米碳管陣列作為電極材料，並以不同的溫度對材料進行退火，而後量測其電化學電容特性並加以比較，其中，披覆二硫化鉬之蜂巢狀奈米碳管陣列以 700℃退火一小時
後可得到最佳實驗電容值 425 F/g，與純奈米碳管電極之 4.7 F/g 相比，足足有約 90 倍的成長。

In this experiment, we chose stainless substrate (SUS304) as the basis, and carbon nanotubes (CNT) bundle arrays were grown on it. After that, we used chemical vapor deposition to synthesis MoS2 coating on the carbon nanotube bundle arrays, we would use it as the electrode in the following electric doublelayer capacitor (EDLC) measurement. CNTs have lots of characteristics, such as high electrical conductivity, high chemical stability, and high specific surface area etc. Through the Photolithography, we defined the growth area of CNTs which looks like honeycomb. Honeycomb-shaped CNTs can increase the contact area between electrode and electrolyte, in this way, we could get better performance in EDLC measurement. Two-dimensional transition metal dichalcogenides (TMDs) can increase the effective area in the electrochemical reaction due to their layered structure, more than that, it also reduces the path of electrons/ions transfer to improve the performance of electrode in electrochemistry. MoS2 is usually used in electrochemical experiments because of its excellent electrochemical activity and high theoretical capacitance value. Above all, we compounded Honeycomb-shaped CNTs and MoS2 as the electrochemical electrode, after annealing our samples in different temperature, we measured and compared their EDLC capacitance. In the end, we noticed that MoS2/CNTs was annealed at 700℃ for 1 hour could get the best capacitance value of 425 F/g, which is 90 times higher than only using CNTs as the electrode (4.7 F/g).
