Center for Functional Nanomaterials Transformation of Carbon Dioxide to Energy Storage Materials at Mild Conditions Prof. Jae W. Lee Department of Chemical and Biomolecular Engineering Korea Advanced Institute of Science and Technology (KAIST) Friday, November 1, 2013 11:00 am Bldg. 735 ‚Ä" Conference Room B While carbon dioxide (CO2) is a major contributor to global warming, it can be a sustainable and cheap carbon source. Thus, there will be potentials for CO2 to be converted to useful chemicals or liquid fuels by either catalytic or non‚Äźcatalytic reactions. In this talk, we will show our recent work on derivation of boron‚Äźnitrogen co‚Äźdoped graphene oxide from low‚Äźpressure CO2 by using ammonia borane as a reduction agent. Then, we will introduce boron‚Äźdoped porous carbons (BPCs) that are synthesized from carbon dioxide (CO2) reaction with sodium borohydride as a reduction agent at 1 atm and 500 oC. Using thermal analyses of the reaction in TGA‚ÄźDSC combined FT‚ÄźIR, we will elucidate the reaction mechanism. The incorporation of boron atoms into the carbon lattice will be confirmed by using X‚Äźray photoelectron spectroscopy. Electrochemical measurements of BPCs will provide some promises for their potential applications as fuel cell electrodes and supercapacitor electrodes.
