Abstract

In order to explore the possible catalytic activity of Co, Zn ferrite catalysts, the current work explores their morphological and compositional features. The extraordinary surface area was attributed to the development of irregular nanocrystalline particles with sheet-like shapes, as indicated by field emission scanning electron microscopy (FE-SEM) study. The presence and appropriate ratios of Co, Zn, Fe, and O were verified by energy-dispersive X-ray spectroscopy (EDS), reflecting catalyst stoichiometry and purity. The polydispersity of the catalysts was further revealed by high-resolution transmission electron microscopy (HR-TEM) micrographs, which showed a wide range of particle sizes shaped as quasi-spherical, octahedral, and cubic. These results offer insightful information about the catalysts' structural properties and point to their possible utility in a range of catalytic applications particularly for the volatile organic compounds (VOC).
