Nanostructured carbon-metal hybrid aerogels from bacterial cellulose

Infiltration of nickel(II) hydroxide inside a bacterial cellulose gel followed by thermal treatment gives rise to highly crystalline nickel nanoparticles that remain associated with the generated carbon nanofibers. The involved mechanism, ascribed to a carbothermal reduction, takes place at an excep...
