Graphene/MgO composite was studied to develop warm CO 2 capturer. The structure of doped MgO was examined with XRD and nitrogen adsorption‐desorption, and its basicity was assessed with instantaneous adsorption and temperature programmed desorption (TPD) of CO 2 . The surface area of MgO was increased ten times by adding graphene, and the CO 2 adsorption capability was also significantly enhanced. A new method combined CO 2 instantaneous adsorption and TPD technique is proposed here to examine the adsorptive sites of the MgO sorbent, exploring the property‐function relation of the CO 2 capturer.
