AbstractSince the onset of the industrial revolution, fossil fuels have been the primary source of energy generation, and the continued exploitation of fossil fuels has led to an increase in the amount of atmospheric carbon dioxide. A lot of research currently focuses much on decreasing dependence on fossil fuels by replacing them with green energy. However, this technique poses a number of challenges, such as the need for improved infrastructure and technology and the high market penetration of renewable energy technologies. Capturing and converting carbon dioxide using electrochemical approaches can help to stabilize atmospheric greenhouse gas levels and create a positive future for the transformation of carbon dioxide into a number of value-added products. The conversion of carbon dioxide via electrochemical approach is a major challenge, and consideration must be given to the development and production of low-cost, stable, and highly efficient electrocatalysts. Hence, this review presents an overview of the current developments in the electrochemical conversion of carbon dioxide. In addition, this study discusses the current progress of electrocatalysts, in particular, the homogeneous and heterogeneous catalyst, which has a high level of activity and selectivity of low overpotential preferred products. The overview of the mechanisms and kinetics of the carbon dioxide reduction using the computational method are also addressed.

Cement production is currently the largest single industrial emitter of CO2, accounting for ∼8% (2.8 Gtons/y) of global CO2emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2emissions due to the decomposition of CaCO3to CaO and that due to combustion of fossil fuels (primarily coal) in calcining (∼900 °C) and sintering (∼1,450 °C). Here, we demonstrate an electrochemical process that uses neutral water electrolysis to produce a pH gradient in which CaCO3is decarbonated at low pH and Ca(OH)2is precipitated at high pH, concurrently producing a high-purity O2/CO2gas mixture (1:2 molar ratio at stoichiometric operation) at the anode and H2at the cathode. We show that the solid Ca(OH)2product readily decomposes and reacts with SiO2to form alite, the majority cementitious phase in Portland cement. Electrochemical calcination produces concentrated gas streams from which CO2may be readily separated and sequestered, H2and/or O2may be used to generate electric power via fuel cells or combustors, O2may be used as a component of oxyfuel in the cement kiln to improve efficiency and lower CO2emissions, or the output gases may be used for other value-added processes such as liquid fuel production. Analysis shows that if the hydrogen produced by the reactor were combusted to heat the high-temperature kiln, the electrochemical cement process could be powered solely by renewable electricity.
