Applications of bacterial cellulose as precursor of carbon and composites with metal oxide, metal sulfide and metal nanoparticles: A review of recent advances
Résumé
A review. This mini review is limited to recent studies (last 5-10 years) on two major issues, concerning: the prodn. and phys./chem. modification of bacterial cellulose (BC), and its transformation into carbon and integrated synthesis of metal oxides (TiO2, ZnO, Fe3O4, etc.), metal sulfide (ZnS, CdS, etc.) and metal nanoparticles (Au, Ag, Pt, Pd, etc.) within bacterial cellulose nanoribbons network. We believe that the crossover of these two domains could be of considerable interest in the view of improving the performance of materials prepd. with bacterial cellulose. The diversity of these nanomaterials allows targeting of many different properties/applications: electrochem. devices, catalysis and photocatalysis, sensors, etc. After an introduction to the most important chem. and phys. characteristics of BC, prodn. parameters, and its phys. and chem. modifications, we review the use of BC as a precursor of inorg. materials like carbon and composites with metal or inorg. nanoparticles.
