6.  Hybrid Materials Obtained with Iron Oxides

Authors: E.C. Crasmareanu, R. Gheonea, C. Mak, V. Simulescu and G. Ilia


Abstract:

This work describes the synthesis of functionalized iron oxide through surface modification of magnetic iron oxide with tailor-made phenyl-phosphonic acid. Iron oxide were synthesized by precipitation method in “green” conditions, using water as solvent, and by thermal decomposition. The surface modification process was achieved using ultrasonic bath. FT-IR and TGA studies indicate that phenyl-phosphonic acid binds on iron oxides preferably through bidentate bonding mode. They are considered advanced materials, innovative and with promising applications in many areas such as: optical, catalysis, electrical, mechanical, energy, environment, biology or medicine.


Keywords: iron oxide, hybrid materials, phenyl-phosphonic acid, ultrasonic bath, FT-IR, TGA
