異質元素摻雜還原氧化石墨烯電極於儲能裝置之應用研究

為了解決Alkaline fuel cell的問題,作者古安銘 這樣論述:

儲能技術超級電容器的出現為儲能行業的發展提供了巨大的潛力和顯著的優勢。碳基材料,尤其是石墨烯,由於具有蜂窩狀晶格,在儲能應用中備受關注,因其非凡的導電導熱性、彈性、透明性和高比表面積而備受關注,使其成為最重要的儲能材料之一。石墨烯基超級電容器的高能量密度和優異的電/電化學性能的製造是開發大功率能源最緊迫的挑戰之一。在此,我們描述了生產石墨烯基儲能材料的兩種方法,並研究了所製備材料作為超級電容器裝置的電極材料的儲能性能。第一,我們開發了一種新穎、經濟且直接的方法來合成柔性和導電的 還原氧化石墨烯和還原氧化石墨烯/多壁奈米碳管複合薄膜。通過三電極系統,在一些強鹼水性電解質,如 氫氧化鉀、清氧化鋰

和氫氧化鈉中,研究加入多壁奈米碳管對還原氧化石墨烯/多壁奈米碳管複合薄膜電化學性能的影響。通過循環伏安法 (CV)、恆電流充放電 (GCD) 和電化學阻抗譜 (EIS) 探測薄膜的超級電容器行為。通過 X 射線衍射儀 (XRD)、拉曼光譜儀、表面積分析儀 (BET)、熱重分析 (TGA)、場發射掃描電子顯微鏡 (FESEM) 和穿透電子顯微鏡 (TEM) 對薄膜的結構和形態進行研究. 用 10 wt% 多壁奈米碳管(GP10C) 合成的還原氧化石墨烯/多壁奈米碳管薄膜表現出 200 Fg-1 的高比電容,15000 次循環測試後保持92%的比電容,小弛豫時間常數(~194 ms)和在2M氫氧化

鉀電解液中的高擴散係數 (7.8457×10−9 cm2s-1)。此外,以 GP10C 作為陽極和陰極,使用 2M氫氧化鉀作為電解質的對稱超級電容器鈕扣電容在電流密度為 0.1 Ag-1 時表現出 19.4 Whkg-1 的高能量密度和 439Wkg-1 的功率密度,以及良好的循環穩定性:在,0.3 Ag-1 下,10000 次循環後,保持85%的比電容。第二,我們合成了一種簡單、環保、具有成本效益的異質元素(氮、磷和氟)共摻雜氧化石墨烯(NPFG)。通過水熱功能化和冷凍乾燥方法將氧化石墨烯進行還原。此材料具有高比表面積和層次多孔結構。我們廣泛研究了不同元素摻雜對合成的還原氧化石墨烯的儲能性能

的影響。在相同條件下測量比電容,顯示出比第一種方法生產的材料更好的超級電容。以最佳量的五氟吡啶和植酸 (PA) 合成的氮、磷和氟共摻雜石墨烯 (NPFG-0.3) 表現出更佳的比電容(0.5 Ag-1 時為 319 Fg-1),具有良好的倍率性能、較短的弛豫時間常數 (τ = 28.4 ms) 和在 6M氫氧化鉀水性電解質中較高的電解陽離子擴散係數 (Dk+ = 8.8261×10-9 cm2 s–1)。在還原氧化石墨烯模型中提供氮、氟和磷原子替換的密度泛函理論 (DFT) 計算結果可以將能量值 (GT) 從 -673.79 eV 增加到 -643.26 eV,展示了原子級能量如何提高與電解質

的電化學反應。NPFG-0.3 相對於 NFG、PG 和純 還原氧化石墨烯的較佳性能主要歸因於電子/離子傳輸現象的平衡良好的快速動力學過程。我們設計的對稱鈕扣超級電容器裝置使用 NPFG-0.3 作為陽極和陰極,在 1M 硫酸鈉水性電解質中的功率密度為 716 Wkg-1 的功率密度時表現出 38 Whkg-1 的高能量密度和在 6M氫氧化鉀水性電解質中,24 Whkg-1 的能量密度下有499 Wkg-1的功率密度。簡便的合成方法和理想的電化學結果表明,合成的 NPFG-0.3 材料在未來超級電容器應用中具有很高的潛力。

氧化鎳負載於鋯酸稀土金屬氧化物Ln2Zr2O7(Ln= La,Nd,Gd,Ho)對於乙醇氧化蒸氣重組反應之影響

為了解決Alkaline fuel cell的問題,作者謝育平 這樣論述:

本研究以Glycine-nitrate Combusion法合成Ln2Zr2O7(LnZO),Ln=La、Nd、Gd、Ho,La2Zr2O7(LZO)、Nd2Zr2O7(NdZO)為燒綠石結構;Gd2Zr2O7(GdZO)、Ho2Zr2O7(HoZO)為螢石結構,使用該法製備的粉體透過2種製程來製作壓碇及注漿2種載體。透過BET測量載體比表面積上,載體前趨物的粉體夠小,則2種製程對於比表面積的影響不大,比表面積大部分以壓碇載體大於注漿載體,數值都介於一個數量級之間。效率測試部分,本研究以氧化鎳為觸媒,含浸在2種壓碇及注漿載體上,個別進行乙醇氧化蒸氣重組反應(OSRE)產氫,在C/O=0.7,

啟動溫度為500°C和GHSV=120,000h-1的條件下,在含浸絕對重量相同的氧化鎳在4種LnZO的壓碇及注漿載體上,2種載體活性表現相似,且在NiO/GdZO有最佳氫氣選擇率121%(0.7),乙醇轉化率為100%(0.5)。活性表現的因素有以下兩種可能:1. 載體的酸鹼特性會影響氣體的吸附表現,在NiO/GdZO上顯示,可以有效地吸附CO,並且促進WGS反應的發生。2. 載體結構有2種,燒綠石以及螢石結構,螢石結構因為金屬陽離子會共同填站在同一位置上,因此有較多的氧空缺生成,強化氣體的吸附,使得活性表現獲得進一步的提升。最佳的觸媒載體組合為NiO/GdZO,在100小時的長

時間活性測試後,氫氣選擇率為88%,乙醇轉化率為100%轉換。
