Types of carbon supplies were observed: (1) (two)Catalysts 2021, 11, x FOR PEER Critique(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 were formed by way of a base-growth mode exactly where Ni particles anchored 10 of 17 into the catalyst assistance and CNTs grew depending on the surface of Ni NPs, Figure 9D; C, as shown in Some bamboo-like CNTs were formed at higher temperature, i.e., 800 Figure 10A,B; Some metal-encapsulated carbon composites were observed at larger tempera4) Some metal-encapsulated carbon composites had been observedat higher temperature, Sordarin MedChemExpress 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 5) It was observed some significant size NPs have numerous crystal faces exactly where CNTs grew towards towards unique orientations (Figure 10D). grew diverse orientations (Figure 10D).Figure 9.

The H2-TPR profiles of Ni/SBA-15 shown in Figure 4 confirmed that there had been two kinds of Ni particles on the SBA-15 support: 1 weakly interacting with SBA-15, as evidenced by the low reduction temperature peak at 20080 ; and yet another robust interacting with SBA-15, indicated by the TPR peak at high temperature region in between 400 and 700 . When carbon atoms had been released from the CH4 decomposition around the surface from the Ni NPs strongly anchored in to the SBA-15, carbon nanotubes have been constructed on the Ni surface via the base-growthCatalysts 2021, 11, x FOR PEER REVIEW11 ofCatalysts 2021, 11,follow the tip-growth mode. These final results are related to these observed for Ni/Ce-MCM10 41 catalysts reported by Guevara et al.

[34], exactly where each, the tip-growth as well as the basegrowth modes of CNTs are proposed.Figure ten. TEM micrographs of Ni/SBA-15 catalysts. (A,B) CNTs with bamboo-like shape Figure 10.
