Abstract
Methods for making metal particle-chitin composite materials are described. The methods can comprise contacting an ionic liquid with chitin, thereby forming a mixture; contacting the mixture with a non-solvent, thereby forming a chitin substrate in the non-solvent; collecting the chitin substrate from the non-solvent; deacetylating the collected chitin substrate, thereby forming a deacetylated chitin substrate; contacting the deacetylated chitin substrate with a metal salt, thereby forming an impregnated precursor composite material; and contacting the impregnated precursor composite material with a reducing agent, thereby reducing the metal salt to form a plurality of metal particles dispersed on the chitin substrate and forming the metal particle-chitin composite material.
