Raman spectra of hybrid materials based on carbon nanotubes and Cs3PMo12O40

A route for the synthesis of hybrid materials using multiwalled carbon nanotubes (MWCNTS) and Cs3PMo12O40 was confirmed. The Cs3PMo12O40 salt was synthesized from H3PMo12O40·14H2O and CsCl. All compounds were characterized by Raman spectroscopy. The synthesis method can produce a chemically stable Cs3PMo12O40 molecule and pure and oxidized MWCNTS. Raman spectroscopy showed that the chemical interaction between MWCNTS and Cs3PMo12O40 was essentially of electrostatic nature. Raman spectra obtained with different wavelengths showed thermal decomposition of H3PMo12O40·14H2O (raw materials) from laser heating process. On the contrary, the synthesized compound (i.e. Cs3PMo12O40) was stable under the experimental conditions.
