Abstract
In the present work, two types of magnetic-nanostructure catalysts were synthesized for highly efficient methodologies in organic chemistry processes [1]. The vital motivation for synthesizing nano-catalyst is to promote sustainability, enhance catalysis properties and provide great advantage to catalytic applications. The unique properties of magnetic nano-catalyst such as; easy separation methodology by external applied magnetic field and the recyclability expands these class of nano-catalysts to wide area of applications. In fact, the combination between sustainable catalysis and magnetic properties yields an extremely powerful and environmentally green organic processes [2]. synthesis of both nano- catalyst -in the current work- includes the metal ferrite oxide in nano- measurements. The silica supported nano-catalyst afford functionalization options to metal ferrite oxide nano-catalyst. At the first, nano-catalyst made of copper ferrite components (CuFe2O4 NP) was synthesized by co- precipitation (CPT) method. Subsequently, the sol-gel method was applied to synthesized the silica coated copper ferrite magnetic nanoparticles CuFe2O4@SiO2. A selection of characterization techniques were chosen to understand and investigate the changes occur in physical properties in both types of nano-catalysts. The study focuses on their structural, morphological and physical properties. Depending on the following techniques; transmission electron microscopes TEM, scanning electron microscopes SEM,
X-ray diffraction XRD, Energy-dispersive X-ray EDX, fourier transform infrared spectroscopy FTIR and the Zeta potential which may be a useful indication for catalytic performance of hetero nano-catalysts [3].
