... temperature of PEG 2000. The reduction of PEG 2000 concentration caused by quick evaporation may be a reason for the failure of porous structure’s fab- rication. Decreasing the reaction temperature ... of PEG 6000. Conclusions In summary, the Fe 3 O 4 nanoporous particles are synthe- sized in the presence of polymer PEG 4000 by thermal decomposition of iron acetylacetonate. Th...
