Metal oxide nanoparticle embedded porous carbon composite materials have various uses, including as catalyst supports, sensor, and adsorbents, because of their good stability and unique porosity. Despite their importance, the procedures for the synthesis of metal-oxide nanoparticle embedded porous carbon composites have not been widely studied. We present a facile synthesis method for metal oxide embedded porous carbon compound via simple pyrolysis of metal-organic frameworks (MOFs, MIL-100). The porosity of the composite material was controlled by addition of carbon source (such as furfuryl alcohol) to the MOF. We found that the incorporation of an additional carbon source and further wash process can be used to control the chemical composition and pore structure of the resulting carbon materials. In addition, the composition and the rate of flowing gas during pyrolysis determine the oxidation state of the resulting metal oxides. The prepared composite materials were characterized by SEM, TEM, and PXRD analysis revealing that the nanoparticles have a single phase and uniform size. One of the prepared materials can be used as an electrode of Li-ion battery. Details of our recent work will be presented
