造法にある。[Means for Solving the Problems] The present invention has been made to achieve the above object, and its gist is to introduce a transition metal compound and an organic compound into a pyrolysis furnace, and to generate ultrafine particles of a transition metal element. In a method of producing carbon transition as a sheet by vapor phase pyrolysis of an organic compound, vapor phase carbon uses a transition metal salt of a carboxylic acid having 3 or more carbon atoms as a transition metal compound serving as a sheet source! ! It is in the manufacturing method of navy blue.

ル酸は、例えばＦ・塩とした場合、Ｆ・を５ｗｔ％含む
塩を容易、かつ安価に得ることが出来、また毒性も低く
扱い易いのでシート源として好適である。Table 1 Transition metal salts of carboxylic acids (hereinafter referred to as carbone**) contain O in addition to C and H, so there were concerns about whether they would be suitable as sheet sources, but surprisingly they are not much different from metallocenes. The VGCF production rate is obtained. In particular, caprylic acid having 8 carbon atoms is suitable as a sheet source because, for example, when it is made into an F salt, a salt containing 5 wt% of F can be easily and inexpensively obtained, and the toxicity is low and it is easy to handle.
本発明においてカルボン酸塩地の炭素数を３以上とした
理由は、Ｃの数が２以下の、カルボン酸塩は０の炭素に
対する割合が高くなるためか、ＶＧＣＦの生成効率がよ
くないからである。In the present invention, the reason why the number of carbon atoms in the carboxylate base is set to 3 or more is that carboxylates with a carbon number of 2 or less have a high ratio to 0 carbons, or because the production efficiency of VGCF is not good. be.
カルボン酸塩は炭素１１Ｍ源となる有機化合物と併用さ
