Abstract
Official abstract text for this publication.
Provided are nanoporous materials (including nanoporous metals) and related methods of fabricating the disclosed materials. The disclosed materials are useful in supporting chemical reactions, including the on-board production of hydrogen from water by way of contacting the water to the disclosed materials.
First claim
Opening claim text (preview).
What is claimed: 1. A composition, comprising: a hierarchical nanoporous material, the hierarchical nanoporous material comprising macroligaments comprising a metal, the macroligaments comprising interconnected mesoligaments defining nanopores therebetween, the nanopores being open to the environment exterior to the nanoporous material, the macroligaments having an average feature size of from about 0.5 μm to about 1 μm, the mesoligaments having an average cross-section in the range of from about 10 nm to about 20 nm the nanoporous material optionally comprising a metal having a standard reduction potential less than the standard hydrogen electrode (SHE) at 0 V vs SHE, the nanopores being characterized as having an average cross-section in the range of from about 3 to about 100 nm. 2. The composition of claim 1 , wherein the nanopores are characterized as having an average cross-section in the range of from about 10 to about 30 nm. 3. The composition of claim 1 , wherein the composition consists essentially of aluminum. 4. The composition of claim 1 , wherein the nanoporous material is in contact with water. 5. The composition of claim 1 , wherein the hierarchical nanoporous material is free of the oxide form of the metal.
