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


• Flexible micromonoliths 70,000 m−1 as S/V ratio and 20 μm as characteristic length.
• PBI micromonolith-type stack as microstructured support.
• Pt nanoparticles supported on amino functionalized ETS10 crystals.
• Pt based catalytic films on PBI microchannels for n-hexane combustion.
• 75% hexane conversion at 225 °C with 5 ms as gas–solid contact time.

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.
