1. A method of making a nanostructured silicon carbonaceous composite material comprising
contacting a metal-silica precursor with an organic ligand in water to form an aqueous mixture, wherein the organic ligand comprises terephthalic acid derived from polyethylene terephthalate (PET), wherein the metal-silica precursor comprises a metal oxide confined in silica or a metal silicate,
heating the aqueous mixture at a temperature ranging from about 25° C. to 300° C. thereby forming a nano-crystalline metal organic framework/silica intermediate material, and
contacting the nano-crystalline metal organic framework/silica intermediate material with magnesium at a temperature ranging from about 600° C. to 800° C. thereby forming the nanostructured silicon carbonaceous composite material.
