📄 Abstract（原文）
In the context of the intensifying greenhouse effect, the search for effective approaches to the capture and retention of greenhouse gases such as CO, CO₂, and CH₄ has become increasingly relevant. The aim of the present work is to experimentally investigate the absorption capacity of water cryocrystals with respect to CO, CO₂, and CH₄ molecules under low-temperature and vacuum conditions, as well as to analyze the effect of phase transitions of water ice on the kinetics of gas impurity release from the standpoint of the prospective application of these systems in decarbonization technologies. This work presents experimental results on the investigation of the absorption properties of water cryocrystals with respect to CO, CO₂, and CH₄ molecules under deep vacuum and ultra-low temperature conditions (13–200 K). Using temperature-programmed desorption (TPD), mass spectrometry (MS), and laser interferometry, the ability of water ice in various phase states (amorphous, cubic, and hexagonal) to efficiently retain and stepwise release gas impurities has been demonstrated. A correlation between the phase transitions of ice (ASW → Ic → Ih) and the desorption behavior of the molecules has been established. The obtained results confirm the potential of water cryostructures for use as passive or controllable sorbents within prospective decarbonization technologies, environmental monitoring, and gas storage applications.
