Abstract :
In this work, water diffusion in mesoporous alumina was investigated by quasi-elastic neutron scattering (QENS). The dependence of diffusion constant (Dt) of sample upon pore size was observed. On the other hand, conductivities of samples with doping different inorganic salts were investigated. The conductivity increased significantly about 10 to 15 times by doping chloride. The chemical stability of chloride-doped mesoporous Al2O3 was evaluated.
