Desorption of Gasses Induced by Ferroelectric Transition in SbSI Nanowires

For the first time the thermal desorption of $H_2$, $N_2$, $O_2$ and $CO_2$ is presented for antimony sulfoiodide (SbSI) xerogel made up of large quantity nanowires. The desorption has been observed near ferroelectric phase transition established at $T_{c}$=293.0(2) K. The Sievert measurements have shown that the hydrogen uptake is linear function of $H_2$ pressure (when p < 1.1×$10^5$ Pa). The hydrogen storage density in SbSI gel amounted 1.24× $10^{-2}$ wt% (for p = 1.08×$10^5$ Pa at room temperature).
