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:

nanopore aerogel, SiO2, water vapor, IR spectrum
