| Description | In this work, a spherical and hierarchical carbon-based nanocomposite containing dispersed cobalt nanoparticles is introduced. The preparation of this material is based on a facile microwave-assisted synthesis of a cobalt-based metal-organic framework containing a 2,6-naphthalene dicarboxylic linker (labeled as NDC) and its subsequent carbonization at either 600 degrees C or 700 degrees C in an argon atmosphere. The resulting materials exhibit unique morphology and feature small Co nanoparticles with sizes of about 3.1 and 6.0 nm, respectively, evenly dispersed on the carbon matrix. In the methanation of carbon dioxide, these CoNDC-derived nanocomposites achieved a methane formation rate of up to 10.5 mu molCH4 gcat behavior is ascribed to a high content of accessible small metallic cobalt nanoparticles present in the hierarchical structure of CoNDC nanocomposite catalysts, highlighting their promising potential for CO2 utilization in industry. |
