Abstract: Methods for forming an interconnected network of solid material and pores, with metal residing only at the air/solid interface of the interconnected network structure are described. In certain embodiments, nanoparticle decorated sacrificial particles can be used as sacrificial templates for the formation of a porous structure having an interconnected network of solid material and interconnected network of pores. The nanoparticles reside predominantly at the air/solid interface and allow further growth and accessibility of the nanoparticles at defined positions of the interconnected structure. SEM and TEM measurements reveal the formation of 3D interconnected porous structures with nanoparticles residing predominantly at the air/solid interface of the interconnected structure.
