Cellulose scaffolds modulated synthesis of Co3O4 nanocrystals: preparation, characterization and properties
Magnetic Co 3 O 4 nanoparticles were prepared by using microporous regenerated cellulose films as sacrificial scaffolds. The cellulose macromolecules and the porous structure of the films made them used as spatially confined reacting sites where Co(OH) 2 nanoparticles could be synthesized in situ. W...
