Growth of Carbon Nanofibers in Phenolic Resin for Carbon-Contained Refractory Using Different Catalysts

Table 1

Composition of the modified phenolic resin samples.

Sample number	Reference	(a)	(b)	(c)	(d)	(e)	(f)
Phenolic resin/g	5	5	5	5	5	5	5
Different catalyst		Ni	Co	Fe	Ni/Co	Ni/Fe	Fe/Co

Note. The mass of catalyst is 0.75% of the mass of phenolic resin. And mass ratio of the different nitrate in mixture catalysts is 1 : 1.
