| Abstract Scope |
Bimetallic catalyst nanoparticles combining transition and main group metals in a well-organized architecture can facilitate steady and economical catalysis. In this work, the growth of carbon nanotubes (CNTs) was catalyzed by assembling ultra-small bimetallic nanoparticles (BNPs) of Co-Al2O3 into monolayer nanofilm (MNF). MNF was fabricated on plane silicon substrates by the chemical modification method using bifunctional linker molecules. Additionally, the growth of CNTs was promoted by MNF of catalyst BNPs utilizing the chemical vapor deposition method (CVD). Catalyst nanoparticles are capable of growing high-quality, and highly dense carbon nanotube forests which are evidenced by Raman spectroscopy and Scanning electron microscopy. This could facilitate the growth of uniform-length CNTs forest which is desired to enhance the performance of CNTs in sensing and energy storage. |
