A new, prominently stable organic material, L-tryptophanium picrate, was synthesized via a one-step process. The as-prepared sample was characterized by UV-visible, FT-IR, Raman, TGA-DSC, XRD, FE-SEM, EDX, 1H-NMR, 13C-NMR and GC-MS. The significant capacitive behaviour of L-tryptophanium picrate was investigated by cyclic voltammetric studies (CV), galvanostatic charge–discharge tests and impedance
通过一步法合成了一种新的,显着稳定的有机材料苦味酸L-色氨酸。所制备的样品的特征在于紫外可见光,FT-IR,拉曼光谱,TGA-DSC,XRD,FE-SEM,EDX,1 H-NMR,13 C-NMR和GC-MS。在1 M的KOH水溶液中,通过循环伏安研究(CV),恒电流充放电测试和阻抗谱技术,研究了L-色氨酸甲基吡啶的显着电容行为。新制造的L-色氨酸甲基吡啶鎓电极材料在1 A g -1的电流密度下表现出263 F g -1的优异比电容。此外,即使在连续2000次充电/放电循环后,它仍显示出约92%的电容保持率。此外,所制备的电极材料说明了电化学可逆的行为。此外,合成的材料在选定的电势窗口下显示出良好的电化学性能。因此,证明了所制造的电极是用于高性能能量存储应用的有前途的替代电极。
