Drift study of hematite adhered onto silver and mercury

Diffuse reflectance Fourier transform infrared spectroscopy (DRIFT) has been used as a tool to study colloidal hematite adhered onto silver and mercury electrodes from suspensions using sodium perchlorate as electrolyte. The results show a shift of one lattice vibrational band toward higher energies...

The results show a shift of one lattice vibrational band toward higher energies when hematite particles are attached onto the metal surface, the shift being more important for mercury.
