Study On The Oriented Preparation And Catalysis Of Layered Double Hydroxide Films

Layered double hydroxides (LDHs) are a calss of anionic lamellar functional materials. They can be used as high activity catalysis, adsorption, separation, biology and medicine materials. Otherwise, they also display potential application in the fileds of optic, electrical and magnetical materials and can be used as chemical micro devices. The filming and immobilizing of functional LDH materials on some certain substrates would provide a novel route to fabricate optic, electrical, magnetical and catalysis reactor devices. In our work, the LDHs were immobilized on polystyrene, mica and aluminium substrates, respectively. The oriented filming and immobilizing manchanisms were investingated. For developping LDH monolithic catalysts, the catalysis activity of activated LDHs that immobilized on mica and LDH films on aluminium was studied by the self-condensation of acetone. For comparison, the catalysis activity of activated LDH particles was also studied in detail. The main results are as follows:...
