Abstract
Disclosed here is a method for making a nanoporous material, comprising aerosolizing a solution comprising at least one metal salt and at least one solvent to obtain an aerosol, freezing the aerosol to obtain a frozen aerosol, and drying the frozen aerosol to obtain a nanoporous metal compound material. Further, the nanoporous metal compound material can be reduced to obtain a nanoporous metal material.
Claims18
A method for making a nanoporous metal material, comprising:
- aerosolizing a solution comprising at least one metal salt and at least one solvent to obtain an aerosol;
- freezing the aerosol to obtain a frozen aerosol;
- drying the frozen aerosol to obtain a nanoporous metal compound material;
- and
- converting the nanoporous metal compound material to a nanoporous metal material, wherein the nanoporous metal material comprises at least about 40 wt. % of elemental metal.
