Abstract

• This thesis aims to preparation of environmentally-friendly modern solid acid nanocatalysts and the study of structural characterization, chemical catalytic activity, adsorption catalytic activity of prepared metal organic frame works nanocatlysts.
The thesis contains: theoretical introduction about metal organic framework catalysts (MOFs), literature survey and aims of the work.
• The experimental part include preparation of Fe-MOFs, Mg-MOF , (Fe/ Mg)Bi-MOFs, Ag-MOF and (Ag / Mg)Bi-MOFs, (Ag /Fe)Bi-MOFs nanocatalysts. Structure characterization of the prepared nanocatalysts was determined using XRD, TEM, SEM, FT-IR techniques.
• The XRD, TEM , SEM and IR results proved formation of Mg -MOF, Fe-MOF , (Fe/ Mg )Bi-MOF, Ag-MOF and (Ag / Mg)Bi-MOFs, (Ag /Fe)Bi-MOFs nanocatalysts with well crystalline. Fe-MOFs and Mg-MOFs have octahedral structure.
• The titration results indicate that Fe-MOFs, Mg -MOFs, (Fe/ Mg)Bi-MOFs, Ag-MOF and (Ag / Mg)Bi-MOFs, (Ag /Fe)Bi-MOFs nanoctalysts have very strong acid sites (> 100 mV).
• We study the catalytic activity of the prepared nanocatalysts by catalysis of two chemical reactions: synthesis of 3.4-dihydropyrimodinone and dibenzo -xanthene
• We study adsorption of 4 heavy metals (Pb2+, Cd2+ and Cu2+) as inorganic pollutants.
• We study number of effects on adsorption activity.
• Keywords:
nanocatalysts, metal organic frameworks, adsorption, catalytic activity.
