Application of Biobased Substances in the Synthesis of Nanostructured Magnetic Core-Shell Materials

We propose here a novel green synthesis route of core-shell magnetic nanomaterials based on the polyol method, which uses bio-based substances (BBS) derived from biowaste, as stabilizer and directing agent. First, we studied effect BBS concentration size, morphology, composition iron oxides nanoparticles obtained in presence via method (MBBS). Then, proof concept, further coated MBBS with mesoporous silica (MBBS@mSiO2) or titanium dioxide (MBBS@TiO2) to obtain nanostructured materials. All materials were deeply characterized diverse physicochemical techniques. Results showed that both size nanocrystals their aggregation strongly depend used synthesis: higher BBS, smaller sizes oxide nanoparticles. On other hand, as-prepared applied good performance different systems. In particular, MBBS@SiO2 be an excellent nanocarrier ibuprofen successful adsorbent methylene blue (MB) aqueous solution. MBBS@TiO2 was capable degrading MB same efficiency pristine TiO2. These results encourage use types methods since they could reduce fabrication costs environmental impact.
