“…Due to their physical structure the materials take an intermediate position between solid adsorbents and pure metallic salts and can be manufactured in such a way as to demonstrate the best features of both systems. So far, composites for ammonia sorption have been synthesized with CaCl 2 impregnated into various matrices, such as activated carbon [3,4], the synthetic carbon Busofit [5], CaSO 4 [6,7]. These materials have greater sorption capacity compared with non-impregnated matrices and better kinetics than the bulk salt [8].…”

“…Moreover, a host matrix provides a network for efficient transfer of heat and reagent which greatly enhances these processes, as it was conceived and reached for composite sorbents of ammonia "salt + expanded graphite" (Mauran et al, 1994;Wang et al, 2006) or "salt + Busofit" (Vasiliev et al, 1996).…”

“…Additional ways for nanotailoring appear for two phase structures, e.g., composites "a salt in a nanoporous matrix" (Aristov et al, 1996Aristov et al, 2005;Vasiliev et al, 1996Vasiliev et al, , 2001Sharonov et al, 2006;Gordeeva et al, 2007a;Zhong et al, 2007;Wang et al, 2006). If the sorbate is water, these materials are called selective water sorbents (SWS).…”

The brief review of innovative materials for adsorptive pumping and storage of low temperature heat as well as current trends in this field showed their great potential. To implement it in the near future it is reasonable to follow two complementary lines: (a) systematic testing for this application novel adsorbents initially developed for other targets (gas drying, separation, etc.), and (b) tailoring of new specific porous materials adapted just to variety of adsorptive cooling, heating and storage cycles under different climatic and boundary conditions. The main idea of the latter approach is that for each particular adsorptive cycle there is an optimal adsorbent, the thermodynamic characteristics of which could allow perfect performance of this cycle. The first step of the analysis is the formulation of requirements to this desirable (ideal) adsorbent. Then, the final step is to design and synthesize a new adsorbent with sorption properties close or even equal to those determined before as perfectly fitting the cycle. Particular examples of nanotailoring of adsorption properties are given for two phase materials, composites "a salt in a porous host matrix", which can be used as efficient adsorbents of water, methanol and ammonia.

In the 21st century the way to increase the efficiency of new sources of energy is directly related with extended exploration of renewable energy. This modern tendency ensures the fuel economy needs to be realized with nature protection. The increasing of new power sources efficiency (cogeneration, trigeneration systems, fuel cells, photovoltaic systems) can be performed by application of solid sorption heat pumps, regrigerators, heat and cold accumulators, heat transformers, natural gas and hydrogen storage systems and efficient heat exchangers.
