2020-10-15 Ar and C 2 H 2 gases were employed as a carrier gas and carbon source for CNT growth, respectively, whereas the H 2 gas can function as a reducing agent to facilitate the generation of catalyst and to remove excessive carbon atoms during the CVD process. Fig. 2 shows the morphological change of the BFF-CNT samples with different H 2 flow rates. It can be seen that H 2 plays an important role ...
