Study of the intercalation of lithium salt in gibbsite using time-resolved in situ X-ray diffraction
Time-resolved in situ X-ray diffraction measurements have been used to measure the rate of intercalation of lithium salts (LiX; X = Cl, Br, NO3, OH, and SO4) into Gibbsite (γ-Al(OH)3) giving the layered double hydroxides [LiAl2(OH)6]X·nH2O (X = Cl, Br, NO3, and OH) and [LiAl2(OH)6]2SO4·nH 2O. The te...

| Summary: | Time-resolved in situ X-ray diffraction measurements have been used to measure the rate of intercalation of lithium salts (LiX; X = Cl, Br, NO3, OH, and SO4) into Gibbsite (γ-Al(OH)3) giving the layered double hydroxides [LiAl2(OH)6]X·nH2O (X = Cl, Br, NO3, and OH) and [LiAl2(OH)6]2SO4·nH 2O. The temperature dependence of the rate of intercalation of LiCl yields an activation energy of 27 kJ mol-1. The reaction was also found to be half-order with respect to the initial concentration of LiCl. The rate of intercalation is sensitive to the nature of the anions with the half-lives of the reactions varying from 450 to 4800 s going from Li2SO4 to LiNO3. © 1999 American Chemical Society. |
