Abstract
Novel catalytic membranes and methods of synthesizing the membranes are disclosed herein. The technology involves the synthesis of a new type of permselective membrane that combines a hollow porous support with strategically positioned catalytic and selective transport functions to overcome thermodynamic, kinetic, and thermal obstacles, such as in the production of hydrogen. Sub-micron, dense metallic catalysts and films may be deposited within porous hollow substrates to create the membranes using the techniques of sol slip casting, film coating and electroless plating.
Claims32
A catalytic membrane comprising:
- one or more porous hollow substrates;
- a first porous layer coated on to said one or more porous hollow substrates;
- a first catalyst layer formed on said first porous layer, said first catalyst layer comprising a catalyst;
- and
- a second porous layer deposited on said first catalyst layer, wherein the pores of said second porous layer are filled with said catalyst.
A method of forming a catalytic membrane comprising:
- a) coating one or more porous hollow substrates with a first porous layer;
- b) depositing a catalyst on the first porous layer to form a first catalyst layer;
- c) depositing a second porous layer to cover the first catalytic layer;
- and
- d) filling the pores of the second porous layer with the catalyst to form the catalytic membrane.
