Metal-organic framework (MOF)-derived metal oxide@nanoporous carbon (NC) has drawn increasing interest in recent years since nanoscale metal oxides can be well dispersed in the carbon matrix. Herein, we report the synthesis of MOF-derived MgO/Mg(OH)2@NC, which shows high thermal energy release and storage through reversible chemical transformations. The reversible phase transition triggered by hydration and dehydration was confirmed by powder X-ray diffraction (PXRD) analysis. MOF-derived MgO@NC exhibits an enhanced heat release compared to commercially available MgO because of its large surface area and homogeneous distribution of nanometer-sized MgO in the NC matrix. Details of the work will be presented.
