Vertically Aligned Mesoporous Film Manufacturing method thereof and their Catalytic Applications

摘要

A vertically aligned mesoporous silicate film with site-selective metal deposition from a single polymer precursor and its strong catalytic application. We report an innovative single precursor approach to fabricate vertically aligned mesoporous silicate thin films with high thermal and chemical resistance in large area Si wafers (2 × 3 cm 2). Organo-inorganic block copolymer (BCP) PEO-ss-PVCSZ (polystyrene oxide-ss-polyvinylcyclicsilazine) with complex designed chemically cleavable disulfide bridges is oriented silicate nanoporous film Newly synthesized, single precursors for the formation of mesostructures directly on substrates through solvent annealing self-assembly followed by block cleavage and simple hydrolysis conversion from polymer to siliceous phase at room temperature .
