CO2 insertion under pressure: In silver-exchanged natrolite, a low and technically achievable onset pressure-induced hydration has been established at 0.4 GPa accompanied by an approximately 5 % expansion in the unit-cell volume (see figure). This unique property has been utilized to trap CO2 under pressure in nominally non-penetrating natrolite pores.
