Abstract
The purpose of the present invention is to provide a catalyst support with which it is possible to produce a high-quality fibrous carbon nanostructure. The purpose of the present invention is to provide a catalyst support used when producing a fibrous carbon nanostructure, the catalyst support comprising a carrier and a catalyst layer formed on the carrier, the catalyst layer including a metal-containing compound, and the difference ΔYI in yellowness expressed by the formula being 3-20, where YIA is the yellowness of the carrier, and YIB is the yellowness of the catalyst support. ΔYI=YIB−YIA.
Claims7
A method of producing catalyst supports for use in producing fibrous carbon nanostructures, the catalyst supports comprising:
- carriers and a catalyst layer formed on the carriers, wherein
- the catalyst layer comprises a metal-containing compound, and wherein
- the method comprises a step of adjusting a difference ΔYI in yellowness expressed by the formula ΔYI=YIB−YIA to be 3 or more and 20 or less, where YIA is a yellowness of the carriers, and YIB is a yellowness of the catalyst supports.
