Carbon Materials Containing Iron Oxide Nanoparticles. a Synthetic Approach
نویسنده
چکیده
An anthracene oil-based pitch, supplied by Industrial Química del Nalón, S.A was used as carbon matrix precursor (softening point of 112oC; elemental analysis: C: 93.6 %, H: 4.4 %, N, 1.0 %, S, 0.5% and O, 0.5%). The iron oxide nanoparticles were obtained following different procedures: (i) toluene reflux of Fe(CO)5 with Pluronic P127 in the presence of H2 [1]; (ii) treatment of a mixture of FeCl3.H2O and FeCl2.4 H2O with concentrated aqueous ammonia, precipitation and stabilization with lauric acid [2]; and (iii) a sol-gel procedure using tetraethoxysilane (TEOS) and an iron nitrate aqueous solution [3].

متن کاملSynthesis methods to prepare single- and multi-core iron oxide nanoparticles for biomedical applications.
We review current synthetic routes to magnetic iron oxide nanoparticles for biomedical applications. We classify the different approaches used depending on their ability to generate magnetic particles that are either single-core (containing only one magnetic core, i.e. a single domain nanocrystal) or multi-core (containing several magnetic cores, i.e. single domain nanocrystals). The synthesis ...

متن کاملControlled multistep purification of single-walled carbon nanotubes.
A controlled and scalable multistep purification method has been developed to remove iron impurity and nonnanotube carbon materials from raw single-walled carbon nanotubes (SWNTs) produced in the HiPco (high-pressure CO) process. In this study, iron nanoparticles, coated by carbon, are exposed and oxidized by multiple step oxidation at increasing temperatures. To avoid catalytic oxidation by ir...
