Forms of carbon supplies have been observed: (1) (2)Catalysts 2021, 11, x FOR PEER Evaluation(three) (four) (5)Some CNTs had Ni NPs on their tip as shown in Figure 9B,C; and they grew following a tip-growth mode; Some CNTs had been formed via a base-growth mode exactly where Ni particles anchored ten of 17 in to the catalyst help and CNTs grew according to the surface of Ni NPs, Figure 9D; C, as shown in Some Estramustine phosphate Autophagy bamboo-like CNTs were formed at greater temperature, i.e., 800 Figure 10A,B; Some metal-encapsulated carbon composites were observed at higher tempera4) Some metal-encapsulated carbon composites have been observedat higher temperature, forming forming onion-like carbon nanomaterials as shown in Figure 10C,D; ture, onion-like carbon nanomaterials as shown in Figure 10C,D; It was observed some huge size Ni Ni NPs have numerous crystal faces exactly where CNTs five) It was observed some large size NPs have many crystal faces exactly where CNTs grew towards towards unique orientations (Figure 10D). grew unique orientations (Figure 10D).Figure 9.

Quite a few CNTs min a reaction at 600 . base-growth mode on 15 wt Ni/SBA-15 immediately after 440 min of reaction at 600 C.The CNTs formation and development modes may very well be correlated using the interaction strength among the Ni NPs as well as the SBA-15 support. The H2-TPR profiles of Ni/SBA-15 shown in Figure 4 confirmed that there had been two sorts of Ni particles around the SBA-15 help: a single weakly interacting with SBA-15, as evidenced by the low reduction temperature peak at 20080 ; and another powerful interacting with SBA-15, indicated by the TPR peak at high temperature area amongst 400 and 700 . When carbon atoms had been released from the CH4 decomposition around the surface with the Ni NPs strongly anchored in to the SBA-15, carbon nanotubes have been constructed around the Ni surface by means of the base-growthCatalysts 2021, 11, x FOR PEER REVIEW11 ofCatalysts 2021, 11,adhere to the tip-growth mode. These outcomes are related to those observed for Ni/Ce-MCM10 41 catalysts reported by Guevara et al. [21] and also the coprecipitated Ni l and Ni u lof 15 catalysts reported by Shaikhutdinov et al. [34], exactly where both, the tip-growth along with the basegrowth modes of CNTs are proposed.Figure 10. TEM micrographs of Ni/SBA-15 catalysts. (A,B) CNTs with bamboo-like shape Figure ten.
