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.

Porous materials via freeze-casting of metal salt solutions

Described here is a metal-carbon composite, comprising (a) a porous three-dimensional scaffold comprising one or more of carbon nanotubes, graphene and graphene oxide, and (b) metal nanoparticles disposed on said porous scaffold, wherein the metal-carbon composite has a density of 1 g/cmor less, and wherein the metal nanoparticles account for 1 wt. % or more of the metal-carbon composite. Also described are methods for making the metal-carbon composite.

Nanoporous metal-carbon composite

A method of making a nanoporous aerogel includes the steps of providing nanowire suspensions, freeze casting the nanowire suspensions to produce freeze-cast gels, extracting the frozen medium from the freeze-cast gels by freeze-substitution with a solvent to produce wet gels, modifying or functionalizing the wet gels as needed, and drying the wet gels to produce a nanoporous aerogel.
