Monolithic Nanoporous Carbon-supported Fe, Au, Pt and Pd Catalysts from Pyrolysis and Transmetalation via Galvanic Replacemnt of Ferrocene-based Polyamide Aerogels

標題: MULTIFUNCTIONAL POROUS ARAMIDS (AEROGELS), FABRICATION THEREOF, AND CATALYTIC COMPOSITIONS DERIVED THEREFROM

*Abstract: This invention provides a series of new and improved porous polyamide aerogels derived from multifunctional aromatics that combine the high mechanical strength of aramids with the pore structure of aerogels. The polyamide aerogels have a hyperbranched structure, relatively low density, high porosity and may be derived from functionalized monomers having more aromatic groups than functional groups. It also provides a new method for producing the porous polyamide aerogels by polymerizing an aromatic multifunctional carboxylic acid or a ferrocene multifunctional carboxylic acid with a polyfunctional aromatic isocyanate at moderate reaction conditions followed by drying with liquid C02. Polyamide aerogels are useful in the generation of various precious metal catalysts. Thus, monolithic nanoporous carbon-supported Fe, Au, Pt, Pd, Co, Ni, Ru, and Rh catalysts are focal points of this invention, which are derived by pyrolysis and Trans metalation via galvanic replacement of ferrocene-based polyamide aerogels.
