“…Indeed, sorption, both solid adsorption and liquid absorption, mainly relies on physical and weak chemical bonds, which require limited temperature levels (i.e., below 100 • C) to be split during the charging phase [17]. At the material level, the main activities focus on the development of novel adsorbent materials with enhanced sorption capacity and reduced driving temperature [18]. Particularly, novel composite sorbents, based on a porous structure embedding a hygroscopic salt were deeply investigated, varying both the porous matrix, i.e., vermiculite [19,20], silica gel [21,22], carbon structures [23,24] and the employed salts, i.e., LiCl, CaCl 2 , MgSO 4 , SrBr 2 [20][21][22][24][25][26] .…”
