Facile and one-pot synthesis of magnetic nanoparticles containing mesoporous carbon

Abstract

Magnetic nanoparticles containing mesoporous carbon materials have been synthesized via an one-pot strategy associated with a direct carbonization process from resol, metal ion sources (Co(NO₃)₂·6H₂O, Ni(NO₃)₂·6H₂O) and triblock copolymer F127. The samples exhibited well-ordered 2-dimensional (2-D) hexagonal mesostructures with p6mm symmetry. The Brunauer-Emmet-Teller (BET) surface area and pore size 1.0wt%Co- and 1.0wt%Ni-FDU-15(700) with 1.0 wt% Co and 1.0 wt% Ni content were 700, 528 m²/g and 17.2, 36.4 Å, respectively, after carbonization at 700 °C. The saturation magnetization values of 1.0wt%Co- and 1.0wt%Ni-FDU-15(700) after carbonization at 700 °C were 1.3 and 1.0 emu/g, respectively.
