A family of Composites “Salt inside Porous Matrix” (CSPM) has been considered as promising for adsorption heat transformation (AHT) due to their high sorption capacity and steep sorption isobars. Moreover, the composite nature of these materials provides one with opportunity to intently modify or even tailor CSPM’s sorption properties to fit requirements of particular AHT cycle. In this communication, we extended this nanotailoring approach by confinement of one more salt to the matrix pores. Novel CSPMs based on a binary mixture of lithium, calcium, and barium halides inside various mesoporous matrixes were synthesized with wide variation of the relative salts content. Their phase composition and sorption equilibrium with water, methanol and ammonia vapour (V) were studied by XRD and TG techniques. It was shown that the formation of a homogeneous solid solution of the salts led to the shift of the equilibrium temperature (pressure) of the solvation. When two solid solutions formed inside the pores, they reacted with vapour independently in distinct temperature ranges. Thus, the confinement of binary salt systems to the matrix pores can be an effective tool for designing innovative materials with predetermined sorption properties adapted to AHT cycles.
