20090304920 | SPATIALLY CONTROLLED ATOMIC LAYER DEPOSITION IN POROUS MATERIALS - Methods for the selective deposition of materials within a porous substrate. The methods use the passivating effects of masking precursors applied to the porous substrate. A portion of a pore surface within the substrate is masked by exposing the substrate to one or more masking precursors. The depth of the pore surface that is masked is controllable by regulating the exposure of the substrate to the masking precursor. Application of the masking precursor prevents adsorption of one or more subsequently applied metal precursors about a portion of the pore surface coated by the masking precursor. Less than an entirety of the unmasked pore surface is coated by the metal precursor, forming a metal stripe on a portion of the pore surface. The depth of the metal stripe is controllable by regulating exposure of the porous substrate to the metal precursor. Subsequent exposure of the substrate to a saturating water application oxidizes the deposited precursors. | 12-10-2009 |

20100075827 | CATALYTIC NANOPOROUS MEMBRANES - A nanoporous catalytic membrane which displays several unique features Including pores which can go through the entire thickness of the membrane. The membrane has a higher catalytic and product selectivity than conventional catalysts. Anodic aluminum oxide (AAO) membranes serve as the catalyst substrate. This substrate is then subjected to Atomic Layer Deposition (ALD), which allows the controlled narrowing of the pores from 40 nm to 10 nm in the substrate by deposition of a preparatory material. Subsequent deposition of a catalytic layer on the inner surfaces of the pores reduces pore sizes to less than 10 nm and allows for a higher degree of reaction selectivity. The small pore sizes allow control over which molecules enter the pores, and the flow-through feature can allow for partial oxidation of reactant species as opposed to complete oxidation. A nanoporous separation membrane, produced by ALD is also provided for use in gaseous and liquid separations. The membrane has a high flow rate of material with 100% selectivity. Also provided is a method for producing a catalytic membrane having flow-through pores and discreet catalytic clusters adhering to the inside surfaces of the pores. | 03-25-2010 |
