Porous materials via freeze-casting of metal salt solutions

DWPI Title: Composition used in e.g. ink, comprises nanoporous metal material having preset weight of elemental metal comprising nanoporous particles or foams having preset diameter
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.
Use: Composition. Uses include but are not limited to batteries, catalysis, capacitor electrode, heat sinks, hydrogen storage, filtration, antimicrobial scaffolds, high-energy density physics experiments, inks for additive manufacturing of printed batteries, sensor, desiccant and drug delivery.
Advantage: The composition has excellent specific surface area, tunable density, electrical and thermal conductivity and novel electro/mechanical behavior. The process provides excellent purity, uniformity and yield.
Novelty: A composition comprises nanoporous metal material having 40 wt.% or more elemental metal comprising nanoporous particles or foams having an average or mean diameter of 100 microns or less.
