这里,我们报导一条新途径为很好驱散的做 N 的 mesoporous 碳 nanospheres (MCN ) 的合成经由碳来源(多巴胺) 和硅石来源(tetraethyl orthosilicate ) 的 copolymerization 作为 soft-to-hard templating 策略参考了,它为电气化学的 supercapacitor 展出高效。这个方法分别地克服不受管束的 dispersity 和软模板或难模板的方法的复杂过程的缺点。而且,综合 MCN 特征在一个壶合成期间由高贵金属的 nanoparticles 充实 heteroatom 做 N 和容易的 functionalization。所有上述字符在许多应用程序使同样准备的 MCN 成为一个有希望的平台。表明综合做氮的 MCN 的适用性,这材料为高效的电气化学的 supercapacitor 作为一个电极被采用了,它显示出 223 和 140 的一个电容 ? 在 0.5 和 10 的当前的密度的 F/g ? 在 1 的 A/g ? mol/L KOH 电解质分别地。
Here we report a new approach referred as "soft- to-hard templating" strategy via the copolymerization of carbon source (dopamine) and silica source (tetraethyl orthosilicate) for the synthesis of well dispersed N-doped mesoporous carbon nanospheres (MCNs), which exhibit high performance for electrochemical supercapacitor. This method overcomes the shortcoming of uncontrolled dis- persity and complicated procedures of soft- or hard-tem- plating methods, respectively. Moreover, the synthesized MCNs feature enriched heteroatom N-doping and easy functionalization by noble-metal nanoparticles during the one-pot synthesis. All the above characters make the as- prepared MCNs a promising platform in a variety of applications. To demonstrate the applicability of the syn- thesized nitrogen-doped MCNs, this material has been employed as an electrode for high-performance electro- chemical supercapacitor, which shows a capacitance of 223 and 140 F/g at current densities of 0.5 and 10 A/g in 1 mol/L KOH electrolyte, respectively.
