Abstract

Carbon dioxide can be electrochemically reduced to carbon in molten carbonate salts, promising affordable energy, materials and environmental explorations.

Highlights

  • Two signi cant challenges facing humanity at present are the provision of sustainable and affordable energy, and the avoidance of catastrophic global climate change

  • Indirect reduction of CO2 on the other hand can proceed via the reduction of carbonate ions to carbon and oxide ions in molten carbonate salts

  • The oxide ions in turn react with the CO2 available from the molten salt atmosphere to regenerate the CO32À ions

Summary

Introduction

Ijije received her BEng and MSc degrees from the University of Nottingham in 2010 and 2011 (Malaysia and United Kingdom campuses respectively) She is currently studying for her PhD under the supervision of George Z. Her research focuses on the electrochemical conversion of CO2 to carbon in molten salts and includes both physical and electrochemical characterizations of the produced carbon. She has rst-authored 10 research publications in journals and conferences, and won the Postgraduate Endowed Award from the University of Nottingham in March 2014. Lawrence completed his MEng and PhD in Chemical Engineering at the University of Nottingham in July 2010 and October 2013, respectively. The uses of carbon in energy storage applications such as supercapacitors are well established and play vital roles in the energy industry.[18,19,20] Utilization of the deposited carbon to fabricate supercapacitors for energy storage application is discussed.[13]
