Hollow mesoporous carbon nanospheres doped with fluorine (FHMC) were synthesized for high-performance supercapacitor applications. Monodisperse nanospheres with a copolymeric core-silica shell were produced by charge density matching. The copolymeric chains in the core phase were crosslinked through a Friedel-Crafts reaction, followed by carbonization at 800 °C under a N₂ atmosphere to obtain the core-shell (CSC) nanospheres with a carbon core and silica/carbon composite shell. The silica phase of these core-shell nanospheres was etched selectively during the thermal decomposition of Teflon to synthesize the FHMC nanospheres. During the etching process of silica in the shell phase, the surfaces of the nanospheres were doped with fluorine. The BET surface area was increased significantly from 788 m²/g and 1.31 cm³/g for the CSC nanospheres to 1021 m²/g and 2.55 cm³/g for the FHMC nanospheres. The specific capacitance of the FHMC nanospheres prepared was approximately 174 F/g at a current density of 0.5 A/g. The capacity retention after 10000 charge/discharge cycles at a current density of 1 A/g was approximately 93.6%.

合成了掺有氟的空心中孔碳纳米球（FHMC），用于高性能超级电容器。通过电荷密度匹配制备具有共聚核-二氧化硅壳的单分散纳米球。核相中的共聚链通过弗瑞德-克来福特反应进行交联，然后在N ₂气氛下于800°C碳化，以获得具有碳核和二氧化硅/碳复合壳的核-壳（CSC）纳米球。在聚四氟乙烯热分解过程中，选择性腐蚀了这些核-壳纳米球的二氧化硅相，以合成FHMC纳米球。在壳相中二氧化硅的蚀刻过程中，纳米球的表面掺杂有氟。BET表面积从788 m显着增加² / g且1.31厘米³ /克的纳米球CSC到1021米² / g且2.55厘米³ /克的纳米球FHMC。在0.5 A / g的电流密度下，制备的FHMC纳米球的比电容约为174 F / g。在电流密度为1 A / g的条件下进行10000次充/放电循环后，容量保持率约为93.6％。
