以二氧化硅颗粒为模板，以富氮物质（即吡咯）为碳前驱体，通过纳米铸造策略制备了约1μm的氮掺杂高致密均匀碳微球。这些碳微球具有大量的氮官能团（类似于9wt％N），高达大约1300m（2）g（-1）的高BET表面积，孔隙率主要由微孔组成（
N-doped highly dense uniform carbon microspheres of around 1 mu m have been prepared by a nanocasting strategy using silica particles as template and a nitrogen-rich substance (i.e. pyrrole) as carbon precursor. These carbon microspheres possess a large number of nitrogen functional groups (similar to 9wt % N), a high BET surface area of up to similar to 1300m(2) g(-1) with a porosity made up mostly of micropores (
