MCM-41 deposition on alumina ceramic foams

MCM-41 deposition on alumina ceramic foams

Alumina-based macro-porous ceramic foams were successfully coated with MCM-41 meso-porous materials using an in-situ one step hydrothermal synthesis. Low H 2O/NaOH ratio in the starting mixture leads to a not uniform deposition of the meso-porous materials. Using higher H 2O/NaOH ratio and two cycle...

Zusammenfassung:Alumina-based macro-porous ceramic foams were successfully coated with MCM-41 meso-porous materials using an in-situ one step hydrothermal synthesis. Low H 2O/NaOH ratio in the starting mixture leads to a not uniform deposition of the meso-porous materials. Using higher H 2O/NaOH ratio and two cycles of deposition, a CF with a continuous and thick layer of well-ordered MCM-41 material coating was produced.
