Pt based catalytic coatings on poly(benzimidazole) micromonoliths for indoor quality control

Flexible polybenzimidazole (PBI) micromonoliths prepared by microtransfer moulding are herein proposed for the first time as G-S contactors for catalytic applications. Macroporous polymeric supports with 20 μm as characteristic length and 70,000 m−1 as S/V ratio have been coated by covalent linkage...

Descrição
Resumo:Flexible polybenzimidazole (PBI) micromonoliths prepared by microtransfer moulding are herein proposed for the first time as G-S contactors for catalytic applications. Macroporous polymeric supports with 20 μm as characteristic length and 70,000 m−1 as S/V ratio have been coated by covalent linkage with Pt supported on amino functionalized ETS-10 crystals. As a proof of concept, the catalytic performance of the Pt modified PBI micromonoliths has been successfully demonstrated for indoor quality control, i.e. n-hexane removal at ppm level.
