We report a chemical method by which graphitic carbon is prepared at reaction temperatures as low as 110 degrees C from readily available molecular reagents. This process requires no forcing conditions such as high pressures, intense light, or electrical discharge but is a simple, catalytic organometallic reaction. The carbon forms in a variety of morphologies including graphene sheets and nanotubes. The mild reaction conditions are similar to those routinely employed in homogeneous catalysis; therefore, they will allow the subtle manipulation of reaction variables to give desired morphologies selectively.
我们报道了一种化学方法，通过该方法可在低至110摄氏度的反应温度下，由易得的分子试剂制备石墨碳。该过程不需要诸如高压、强光或放电等强制条件，而是一个简单的催化有机金属反应。碳以多种形态形成，包括石墨烯片和纳米管。温和的反应条件与均相催化中常规使用的条件相似；因此，它们将允许对反应变量进行精细调控以选择性地获得所需形态。
