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.
Claims13
A composition comprising a nanoporous metal material that comprises nanoporous particles or foams having an average or mean diameter of about 100 microns or less, wherein the nanoporous metal material comprises at least about 40 wt. % of elemental metal.
