TiO₂ Surface Coating of Mn-Zn Dopped Ferrites Study

Abstract:

This study deals with TiO₂ coating of powder Mn-Zn ferrite in order to recieve photocatalytic layer on the top of these particles, forming core-shell catalyst. Powder catalysts are of great advance over the world due to the high surface area, considering the kinetics proceeds through heterogenous phase boundary catalysis. However their withdrawal from cleaning systems often requires energetically and economically demanding processes such as filtration and ultrafiltration. Since the ferrite is magnetic, the advantage of such formed core-shell photocatalyst is easibility of removing from photocatalytic decomposition system using external magnetic field. In this study the surface coating is performed, using Ti alkoxides mixtures with nanosized TiO₂ particles and C and Au coating to form film layer of TiO₂ on the surface of ferrite. XRD, SEM – EDS analyses are employed to study surface coating.
