Abstract :
This work is the structural characterization of the copper phthalocyanine (CuPc)/TiO2 nanocomposites. The nanocomposite were prepared by mixing TiO2 nanoparticle and TiO2 nanotube with CuPc suspension. The nanocomposites structure properties were evaluated by means of Raman spectra and EXAFS. From the results show that CuPc can be hosted at the surface of TiO2 and resulted to the bond lengths of CuPc are decreases, especially in first shell and second shell from Cu core atom which were verified by EXAFS spectra.
