Investigation of C-Pd films in hydrogen atmosphere using molecular spectroscopy

In this paper influence of hydrogen on molecular structure of carbonaceous-palladium (C-Pd) films using Raman and FTIR spectroscopy methods has been studied. The special experimental setup (gas cell) was design and realized. The spectra were measured in H2/N2 atmosphere under different gas pressure and flow rate and compared with base spectra measured in air. The noticeable influence of gas flow on intensity of some bands in FTIR spectra were observed. Understanding of role of H2 in interaction with C-Pd film needs other experimental works. Observed phenomenon can be used in construction of optical hydrogen sensor.
