Nitrogen-doped zeolite-templated carbon (N-doped ZTC) is synthesized using NaY zeolite as a template and with acrylonitrile (AN) and propylene as the respective nitrogen and carbon sources. AN is directly mixed with the dried zeolite for adsorption and the mixture is heated to synthesize polyacrylonitrile (PAN) inside the zeolite micropores. Each AN adsorption and polymerization step require only 1 h and both steps were performed in a single container. The resulting zeolite/PAN composite was then subjected to chemical vapor deposition using propylene to fill the zeolite pores with carbon. Subsequently, heat treatment was used for carbonization and the zeolite was removed with hydrofluoric acid. The N-doped ZTC has three-dimensionally ordered and interconnected micropores with a uniform pore size of 1.2 nm, inheriting the structural regularity of the zeolite. The optimum volume of AN is determined to be the same as the total pore volume of the zeolite, which accounts for the high surface area of 3680 m2 g−1 and high structural regularity with a N/C molar ratio of 0.015. The performance of the N-doped ZTC as an electric double-layer capacitor electrode was evaluated using an organic electrolyte and showed a superior performance to undoped ZTC and maintained a high capacitance retention up to 2 A g−1.
以NaY沸石为模板，丙烯腈(AN)和丙烯分别作为氮源和碳源，合成了氮掺杂沸石模板碳(n掺杂ZTC)。将AN直接与干燥的沸石混合进行吸附，并在沸石微孔内加热合成聚丙烯腈(PAN)。每个AN吸附和聚合步骤只需要1小时，两个步骤都在一个容器中进行。所得的沸石/PAN复合材料然后进行化学气相沉积，用丙烯填充沸石孔与碳。随后，采用热处理进行碳化，并用氢氟酸除去沸石。n掺杂的ZTC具有三维有序、相互连接的微孔，孔径均匀，为1.2 nm，继承了沸石的结构规律。确定AN的最佳体积与沸石的总孔容相同，具有3680 m2 g−1的高表面积和0.015的N/C摩尔比的高结构规整性。采用有机电解液对n掺杂ZTC作为双电层电容器电极的性能进行了评价，结果表明，n掺杂ZTC的性能优于未掺杂ZTC，并保持了高达2 a g−1的高电容保持率。
