Abstract
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.
Claims5
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.
