Abstract
Catalytic membranes comprising highly-dispersed, catalytically-active metals in nanoporous carbon membranes and a novel single-phase process to produce the membranes.
Claims17
A catalytically-active nanoporous carbon membrane which comprises:
- a. a support having at least one pore;
- b. a nanoporous carbon membrane which is attached to a surface of the support and comprises a nanoporous carbon material having pores which have a smaller diameter than the diameter of the at least one pore of the support;
- wherein at least one of the pores of the membrane communicates with at least one pore of the support;
- and
- c. a catalytic metal highly dispersed within the nanoporous carbon membrane.
2 more elements
A process for making a catalytically active nanoporous carbon membrane which comprises:
- a. coating a portion of a porous support with a homogenous solution comprising:
- (i) a nanoporous carbon polymeric precursor;
- (ii) an organometallic precursor of a catalytic metal;
- and
- (iii) a non-polar solvent;
- and
- b. pyrolyzing the coating on the support.
