本文报道了一种新的“由软到硬的模板”策略,通过碳源(多巴胺)和硅源(正硅酸乙酯)的共聚合合成了分散性良好的N掺杂介孔碳纳米球(MCNs).该方法克服了复杂软模板和硬模板法难以控制MCNs分散性的问题.获得的MCNs含有丰富的N掺杂物种,且易于实现贵金属纳米颗粒的负载.该MCNs可应用于多领域.本文研究了其超电容特性:在1 mol/L Na OH溶液中,当电流密度为0.4和10 A/g时,该MCNs电极电容可分别达到223和140 F/g.
In this paper, a new “soft-to-hard template” strategy for the synthesis of well-dispersed N-doped mesoporous carbons by the copolymerization of a carbon source (dopamine) and a silicon source (MCNs) .This method overcomes the problems that it is difficult to control the dispersibility of MCNs by the complex soft template and the hard template method.The obtained MCNs are rich in N-doped species and easy to realize the loading of noble metal nanoparticles.The MCNs can be applied to Multi-domain.In this paper, the supercapacitor properties of the MCNs are studied: the electrode capacitance of the MCNs can reach 223 and 140 F / g respectively when the current density is 0.4 and 10 A / g in 1 mol / L NaOH solution.
