Synthesis of Porous Metallic Structure and Its Application for Energy Storage Materials

Porous metal or metal oxide frameworks have been comprehensively applicated to numerous fields such as catalyst, energy storage system, and bio-filtration. Here, we introduce a de-alloying method prior to a facile polymer gel-templating to synthesize a self-supporting porous metal/metal oxide frameworks (e.g. Au, Ag, Ag/CuO, Au/MnO₂, etc.). The template methods based on polymer gel suggest easy preparation of porous metal/metal oxide frameworks, prepared by heating a metal precursor impregnated in polymer gel. Compared to de-alloying Ag65A35 method, polymer gel based soft template serves numerous advantages as follows; 1) facile fabrication of porous transition metal structure, 2) atom economy, 3) high-loading of precious metals, 4) harmless to human and environment, 5) natural abundance, 6) easy to scale-up and control the pore size by differentiate the polymer content ratio, 7) mild reaction conditions, and 8) structural controllability, 9) cost-effectiveness, etc. We report the methodologies to synthesis bicontinuous metal/ metal oxide architectures, derived from porous gel soft templates, and they are applicated to the energy storage system such as, supercapacitor, pseudocapacitor, and battery.
