SYNTHESIS AND GROWTH MECHANISM OF CARBON NANOSTRUCTURES ON A Ni-Fe ALLOY COMING FROM A PEROVSKITE CATALYST PRECURSOR

摘要

Currently, catalytic chemical vapor deposition (CCVD) process is an accepted method for producing a great variety of carbon nanomaterials in bulk such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs), but due to low temperature of synthesis, the crystallinity degree of these materials is poor and the concentration of structural defects are higher than those obtained by others methodologies [1]. However, the presence of these structural defects generated during CCVD process can be seen as a good alternative to orient several possible applications.
