掺杂B_4C对电弧法制备的富勒烯的影响

Influence of B 4Cdoped Anode on the Fullerenes Synthesized by Arc Discharge Method

以高纯石墨棒为阴极，以掺有Ｂ４Ｃ的石墨棒为阳极，用直流电弧法制备富勒烯，对掺杂Ｂ４Ｃ对富勒烯的影响进行了研究．结果表明：（１）掺杂Ｂ４Ｃ使富勒烯的总产率显著下降，且Ｂ４Ｃ的量越大，总产率越低；（２）当孔中掺入Ｂ４Ｃ与石墨的混合物时，产物为纯碳富勒烯，其中大分子富勒烯的相对含量较不掺杂时显著提高；当孔中掺入纯Ｂ４Ｃ时，生成的富勒烯中含有骨架掺硼富勒烯．

With the pure graphite rod as cathode and B 4C doped graphite rod as anode,the fullerenes had been synthesized by DC arc discharge method.The influence of B 4Cdoped anode on the fullerenes had been studied.With the anodes doped with the mixture of B 4C and graphite,the relative content of higher fullerenes increased considerably while the total yield of fullerenes decreased greatly.The borondoped fullerenes can be synthesized by burning the anode doped with pure B 4C.
