This paper describes a catalytically thermal reduction route for the synthesis of tubular graphite cones (TGCs) from the reaction between a mixture of poly(ethylene glycol) and ethylene glycol and magnesium over Fe catalyst decomposed from ferrocene at 640 degreesC. The base of the cones is in the micrometer scale, tapering gradually to form nanometer-sized tips. The hollow cones, which have a shell made up of cylindrical graphite sheets, have been observed by high-resolution transmission electron microscopy (HRTEM), and some Y-junction TGCs were also observed.
