The MgFe2O4 spinel exhibits remarkable magnetic properties that open up numerous applications in biomedicine, the environment and catalysis. nanoparticles are excellent catalyst for carbon nanotube (CNT) production. In this work, we proposed to use nanopowder as a production of 3D macroscopic structures based on CNTs. creation these nanoengineered architectures remains one most important challenges nanotechnology. These systems have high potential supercapacitors, catalytic electrodes, artificial muscles environmental applications. macrostructures formed due an elevated density quantity quality CNTs directly related properties. A heat treatment study was performed produce effective catalyst. Factors such superficial area, inversion, crystallite size, degree agglomeration its correlation with van der Waals forces were examined. As result, ideal CNT determined high-density produced successfully.
