Interest in cellulose derivatives is continuously growing due to the possibility to combine different green chemistry principles: utilization of renewable feed-stocks, materials biodegradability and use of environmentally friendly, regenerable solvents. Much attention has been given to cellulose extraction and processing into various materials using room temperature ionic liquids as solvents. However, only few studies have tried to explore the huge potential of such processes for the preparation of metal oxide�cellulose nanocomposites for direct use or as intermediates in the preparation of metal oxide�carbon nanocomposites. The aim of the present work is to discuss the technical advantages and disadvantages of several preparation routes for cellulose-based nanocomposites doped with metal oxides and to clarify the relationships between the preparation method and the resulting pore structure and nanoparticle distribution. The focus of the study is onto porous cellulose nanocomposites prepared by non-solvent induced phase separation, either from cellulose solutions in ionic liquids or from cellulose acetate solutions in classical solvents followed by deacetylation. Nanoparticles from gas phase synthesis processes have been used and processed as dispersion in the respective polymer solution.Structures of cellulose acetate and corresponding cellulose structure obtained after deacetylation
