Electrochemical preparation of metallic ions/zeolite catalysts

The electrochemical preparation of metallic ions zeolite catalysts (ZO x − M x+ ) is achieved by electroreduction of solid ZO −-Ag + in aqueous solutions according to: x ZO − Ag + + xe + M x+ → ZO − x M x+ + x Ag ° where M x+ is the metallic cation of supporting electrolyte (M x+ = Ni 2+, Cu 2+, etc...

Description
Summary:The electrochemical preparation of metallic ions zeolite catalysts (ZO x − M x+ ) is achieved by electroreduction of solid ZO −-Ag + in aqueous solutions according to: x ZO − Ag + + xe + M x+ → ZO − x M x+ + x Ag ° where M x+ is the metallic cation of supporting electrolyte (M x+ = Ni 2+, Cu 2+, etc…). Some thermodynamic aspects of ion exchange between Ag + and M x+ are studied, via electrochemistry, for mordenite and faujasite type zeolites. Electroanalytical studies of Ag l Ag o , Cu ll Cu l and Cu l Cu o zeolite systems in alkaline and ammoniacal solutions allow the determination of ions concentration within zeolites.
