Abstract
A microporous catalytic material and support prepared under a reducing atmosphere by pyrolysis of an interiorly metal-plated porous polymer to leave the residual microporous tubular-configured metal sheaths of the nodes, fibrils, or other surfaces within the interior of the resulting hollow structure.
Claims12
A microporous catalytic material and support structure for catalytic material comprising a three-dimensional tubular network of metal having micropores throughout, which network comprises the hollow tubular residue of continuous metal plated nodes and fibrils of the interstices of a microporous polymeric material which has been pyrolyzed to remove all materials except said metal material.
A process for preparing a microporous catalytic material and support structure which comprises a three-dimensional network of tubular metal configurations corresponding to the surfaces of the nodes, fibrils, and other surface of the interstices of a microporous polymeric material comprising the steps of:
- (a) metal plating the surfaces of the nodes, fibrils, or other surfaces of a microporous material;
- (b) placing said plated material between porous supporting means;
- (c) pyrolyzing the supported plated microporous material at a temperature and for a time to completely remove all non-metal material;
- and optionally
- (d) chemically removing one or more interior or outer layers of metal.
