This research presents a regulation strategy of constructing heterogeneous bilayer catalyst Fe and Al2O3, namely, Fe-Al2O3, through interfacial interaction particle nucleation, in order to modulate the size catalytic activity sites achieve growth carbon nanotubes (CNTs). Through temperature control, noncatalytically active Fe2O3 clusters on surface Al2O3 are exposed, inducing multiple nucleation its surface. Under synergistic effect confinement at Fe-Al2O3 interface, fabrication small nanoparticles is accomplished. The results indicate that catalytically have diameter approximately 10 nm, grown CNTs 15 nm. Based systematic characterization results, nonactive confined by strong induce their during loading processes, facilitating formation nanoparticles. Additionally, between induces FeAl4O8, thereby enhancing thermal stability In conclusion, targeted offers guidance for low-cost large-scale preparation nanoparticle particles.
