Аннотация:Metal-organic frameworks (MOFs) are promising materials for a number of applications including gas storage and separation. In this work, coordination polymers based on copper and trimesic acid were prepared and characterized by physicochemical methods. Three different synthesis strategies were employed: precipitation at room temperature, hydrothermal method (at different temperatures) and using CO2 as SAS technique (Supercritical AntiSolvent). The obtaining samples was also tested on its capacity in CH4 adsorption at 1 bar and 296 К and 233K.
