Effects of Concentration of Catalyst Precursors on Carbon Nanostructures
It is very important to study the effects of various factors on synthesis of carbon nanomaterials for controlled synthesis, which plays a significant role in realizing desired nanostructures or nanodevices for applications. In this report, we employed iron nitrate solution with different concentration, such as 1 mol/l, 0.1 mol/l, 0.01 mol/l, and saturated iron nitrate solution as catalyst precursor solution and studied the effects of concentration of catalyst precursor solution on carbon nanostructures that were synthesized by ethanol catalytic combustion (ECC) process. We have characterized the as-grown carbon nanostructures by employing scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for deep understanding.
