Preparation of Multilayered Core-Shell FeO-SnO-C Nanoparticles via Polymeric/Silane-Amino Functionalization.

Multilayered core-shell FeO-SnO-C nanoparticles were prepared via surface treatment and carbonization at atmospheric pressure. FeO-SnO nanoparticles were prepared by the carboxylation of the pivotal particles (FeO) with an anionic surfactant to immobilize SnO nanoparticles. A method was proposed to externally surround hydrophilic carbon with amine-forming materials, polyethyleneimine (PEI), and (3-Aminopropyl) triethoxysilane (APTES).
