MCM-41 deposition on alumina ceramic foams

摘要

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/Na0H ratio in the starting mixture leads to a not uniform deposition of the meso-porous materials. Using higher H_2O/Na0H ratio and two cycles of deposition, a CF with a continuous and thick layer of well-ordered MCM-41 material coating was produced.
