一种双表面活性剂模板体系制备氮掺杂多孔炭纳米棒用于超级电容器电极(英文)
A dual-surfactant template system for fabricating N-doped porous carbon nanorods for use as supercapacitor electrodes
【摘要】 在快速聚合过程中,实现一维(1D)多孔炭纳米棒的可控合成对其实际应用至关重要。本文报道了一种ID多孔炭纳米棒的制备方案:以棕榈酸钠和F127在质子化三聚氰胺的促进下组装形成的棒状胶束作为模板;随后,在该棒状胶束的导向下,制备出三聚氰胺基氮掺杂聚合物纳米棒,经炭化处理后得到相应的氮掺杂炭纳米棒。在三电极体系中,以所制氮掺杂炭纳米棒作为超级电容器电极材料时,在电流密度为0.2 A g-1的条件下,比电容达301.66 F g-1,比表面积归一化电容高达67.07μF cm-2。氮掺杂特性和一维形貌赋予该炭纳米棒较低的内阻和良好的稳定性,使其不仅适用于基础研究,也能满足从材料化学到电化学储能等多个领域的实际应用需求。
【Abstract】 The ability to control the preparation of one-dimensional(1D) porous carbon nanorods,especially during rapid polymerization,is key to their practical application.We report a method for synthesizing 1D porous carbon nanorods,characterized by the formation of rod-like micelles that are assembled from sodium palmitate and Pluronic F127,facilitated by protonated melamine,and subsequently converted into melamine-based N-doped polymer nanorods which were carbonized to produce the corresponding N-doped carbon nanorods.The specific capacitance of the supercapacitor used the as-prepared N-doped nanorods as electrode material in a three-electrode system was calculated to be 301.66 F g-1 at a current density of 0.2 A g-1,with an ultra-high specific surface area normalized capacitance of up to 67.07 μF cm-2.The N-doping and their one-dimensionality give the nanorods a low internal resistance and good stability,making them well suited for fundamental studies and practical applications ranging from materials chemistry to electrochemical energy storage.
