Abstract
During catalytic chemical vapor deposition (CCVD), the synthesis parameters and the quality of the catalyst thin film both have to be precisely tuned to synthesize VACNTs in an efficient and reproducible way. In this work, CNT forests were grown on AZO (aluminum doped zinc oxide) glass substrate which was coated via dip coating method with few nanometers thick Al2O3 support layer and bimetallic iron-cobalt catalyst layer. The study of the effect of catalyst composition and synthesis parameters during CCVD growth has revealed the optimal conditions to synthetize CNT forests on AZO. The samples were analyzed via SEM, TEM and Raman spectroscopy to verify the structure and quality of the carbon deposition. Theoretical aspects have confirmed the role of the support layer for conducting substrates during CCVD synthesis; the transformation of the catalyst layer in the presence of hydrogen gas and the growing mechanism of CNTs.
