In view of potential uses in short-term thermochemical heat storage by sorption water vapor, the capacity to release a sufficient amount at appropriate rate Prussian blue analogue (PBA) containing hexacyanocobaltate vacancies has been compared with those 13X type zeolites possessing Na+, Ce3+, Ce4+, or Tb3+ extra-framework compensating cations. The extended structural and surface characterizati...

Zeolite 13X and 5A supported Ni catalysts were synthesized for CO2 methanation using the evaporation impregnation method. The influence of different precursors (nitrate, citrate, acetate) as well calcination temperatures on catalyst properties performance investigated. XRD, SEM-EDX, TEM, STEM-EDX, N2 physisorption, H2-TPR, TPD-NH3 TG/DTA used detailed characterization catalysts. parent structur...

Thermal energy storage includes sensible, latent and thermochemical heat storage. The latter is particularly interesting because the stored as a chemical potential, which reduces loss in long-term applications. viability of systems strongly depends on density material. development high materials thus essential to achieve compact suitable for wide range A new sol-gel composite material investiga...
