Abstract
Methods for making porous materials having metal alloy nanoparticles formed therein are described herein. By preparing a porous material and delivering the precursor solutions under vacuum, the metal precursors can be uniformly embedded within the pores of the porous material. Once absorption is complete, the porous material can be heated in the presence of one or more functional gases to reduce the metal precursors to metal alloy nanoparticles, and embed the metal alloy nanoparticles inside of the pores. As such, the metal alloy nanoparticles can be formed within the pores, while avoiding surface wetting and absorption problems which can occur with small pores.
