Galliation of Zeolites - Liquid-Solid Isomorphous Substitution

1 Galliation of Zeolites - Liquid-Solid Isomorphous Substitution 

Zeolite OFT concentration/(mol/L) Gd203 concentration/(mol/L) Si/Al Si/Ga of galliated zeolite 

Liu[31] reached the following conclusions for the galliation isomorphous substitution and its mechanism on the basis of the aforementioned investigation in zeolite galliation  

In 1991, Dwyer and Karim[32] reported another galliation route, which uses ammonium hexafluorogallate to react with zeolite Y under mild conditions, and the reaction proceeds as shown in Equation (6.29). 

GaF3- + [A104] (zeolite) [Ga04] eolite) + A1F3- (6.29)
