Abstract

In this work, the synthesis of carbon nanotubes/hematite hybrids was investigated. The hybrids were produced by solvothermal method and a systematic study exploring different reaction parameters such as treatment duration, temperature and solvent was performed. Results from different characterization techniques demonstrate that the CNTs were effectively decorated with hematite (α-Fe2O3). The size and concentration of the NPs varies with the reaction parameters and the smallest obtained NPs have ∼100 nm diameter. It was demonstrated that translucent and homogeneous thin films made of the resulting hybrid material can be deposited on indium-tin oxide substrates by electrophoretic deposition or by vaccum filtration.
