Abstract:

The transmission spectra of aerogel with nanopores filled with SO2 and a mixture of H2O and SO2 are studied The measurements were carried out using a Bruker IFS 125 HR Fourier spectrometer in the spectral range 4500–10000 cm-1 at a room temperature. It is found that the filling of nanopores of a sample with SO2 and with a binary mixture of H2O and SO2 molecules affects the absorption bands of the aerogel. This change is reversible: when gases are pumped out, the transmission spectrum of the aerogel sample is restored.

Keywords:
