Zeolite molecular sieve solar cells

Progress in zeolite–water adsorption technologies for energy

Chan et al. [37] studied solar adsorption cooling systems where composite adsorbents, which perfuse "zeolite 13X and CaCl 2," are used that possesses "Na + ions" within its composition. Upon being immersed in a water-based solution of calcium chloride, an ion exchange process occurs among the "Na + ions" in the zeolite and the "Ca 2+ ions" present in
