Title: Renewable resource-based metal-containing materials and applications of the same

Abstract

A method of producing carbon-metal nanocomposites includes (a) treating a material containing at least one o-catechol unit with a first solution of hexamine such that the material becomes hexamine treated; (b) treating the material with a second solution having a plurality of metal ions such that the material becomes metal treated; (c) treating the material with a third solution of alkali such that the material becomes alkali treated; and (d) heating the alkali, metal and hexamine treated material after (a), (b), and (c) for a predetermined period of time such that a plurality of carbon-metal nanocomposites having metal nanoparticles dispersed in the material are produced.
