掺杂碳化钨对电弧法制备的富勒烯的影响

Influence of Doping the Anode with WC on the Fullerenes Prepared by DC Arc Discharge Technique

以掺碳化钨的石墨棒为阳级，以高纯石墨棒为阴极，用直流电弧法合成富勒烯，并对碳化钨对富勒烯的影响进行了研究．结果表明：碳化钨的掺杂不仅能够提高大分子富勒烯的含量，而且不影响富勒烯的总产率．这为大分子富勒烯的研究打下了基础．

With a graphite rod doped by WC as anode and a pure graphite rod ascathode fullerenes had been synthesized by DC arc discharge technique. The influence ofthe dopant on the fullerenes had been studied. The results show that WC favors the formation of larger fullerenes with the total yield of fullerenes unaffected.
