Abstract

This paper presents the synthesis and characterization of magnetite particles covered with titanium dioxide and with two dyes adsorbed on the TiO2 coated surface of the particles. The synthesized materials were structurally characterized using Scanning Electron Microscopy, FT-IR spectroscopy and Energy-Dispersive X-ray spectroscopy..

Keywords
