摘要: In this study we report various new efficient ways to synthesize and modify in situ magnetite (Fe3O4) iron oxide nanoparticles (NPs). Thanks an apparatus especially developed for method of grafting, the NPs have been synthesized functionalized by 3,4-dihydroxyhydrocinnamic acid (DHCA) or 3,4-dihydroxy-L-phenylalanine (LDOPA) one step under hydrothermal conditions using varying concentration ratios ([organic molecules]/[ferrous ferric ions]). The organic molecules were added before after NP synthesis. addition these modifies structure, morphology, oxidation degree growth crystallites. Adding synthesis acidic increases average crystallite size prevents further whereas basic is stopped but a partial maghemite observed. DHCA LDOPA results modification lattice structure does not change size. This underlines importance sequence on NPs.
