文摘
The electrical conductivity of a series of zeolites varying the charge balancing cation, the crystal structure,and the water content has been measured. The current intensity versus voltage profiles of cells constructedwith a conductive glass indium tin oxide anode, an aluminum cathode, and a 50 
m zeolite layer werehighly reproducible. Typically, zeolites exhibit a semiconductor profile, dramatically increasing theelectrical conductivity from the initial insulator regime to a conductive regime at breaking voltages between3.5 and 5 V. By adsorbing on the external surface ruthenium trisbipyridyl, we have assessed that theglobal electrical conductivity of the zeolite films depends on both the external and internal parameters ofthe zeolite. The fact that the overall electrical conductivity has a component due to the intraparticleconductivity is relevant in the context of developing applications for zeolite-encapsulated guests innanotechnology.
