“…Switchable solvents, which chemically bind CO 2 , have also been employed to chemically release CO 2 near an electrode for direct electroreduction. 47 However, to the best of our knowledge, intrinsic electroactivity of CO 2 adducts involving N-C bond cleavage has not been reported.…”

Electrochemical CO 2 conversion has a growing role to play in mitigating rising emissions and identifying novel end-uses for CO 2. We present a combined chemical-electrochemical process, facilitated by a novel electrolyte chemistry, that enables post-combustion CO 2 capture-conversion by integration of conventionally aqueous-based amine sorbents into a nonaqueous, alkali-based electrolyte. This combination imparts emergent discharge activity at high potentials of 3 V at a catalyst-free carbon electrode in a Li battery, advantageously combining two conventionally separate approaches to CO 2 mitigation.

This report documents the outcomes of the Applied Energy Tri-Laboratory Consortium Workshop on Material Challenges and Opportunities that was held July 31 and August 1, 2019, to begin addressing the needs, opportunities, and challenges associated with the development, fabrication, and testing of the needed materials and components for integrated hybrid energy systems (i.e., incorporating nuclear, fossil, and renewables for electric and thermal applications). This was accomplished by assembling the research program leads and principal investigators who support the research and development of new energy system technologies and system integration tools and components at the

“…Liquid phase electrolysis needs further breakthroughs in terms of materials for electrodes, membranes and electrolytes that will allow the higher mass transfer limitations to be overcome, when compared with gas-phase electrolysis. However, this operation mode presents important advantages namely allowing the integration of CO 2 capture and conversion [51] and achieving higher conversions avoiding the costs of separating unreacted CO 2 from gaseous electrolysis products [95,96]. The development of cost-effective 3D materials with pore engineered structures that can be used directly as electrodes is an important nascent R&D avenue.…”

This work reviews the latest developments of cathodes for electrochemical CO 2 reduction, with carbon black, mesoporous carbons, carbon nanofibers, graphene, its derivatives and/or carbon nanotubes as constituents. Electrochemical CO 2 reduction into fuels and chemicals powered by renewable energy is a technology that can contribute to climate change mitigation. Strategies used in this fast-evolving field are discussed, having in mind a commercial application. Electrochemical performance of several materials is analyzed, using in some cases the findings of theoretical computational studies, which show the enormous potential of these materials. Considerable challenges still lie ahead to bring this technology into industrial deployment. However, the significant progress achieved so far shows that further R&D efforts might pay off.C 2019, 5, 83 2 of 26 considering the findings of theoretical computational studies, are in some cases analyzed, when this type of study is available. Knowledge gaps and new promising R&D trends of nanocarbon-based materials development for this application are highlighted. Carbon BlackCarbon black is produced by the incomplete combustion of petroleum heavy fractions. It is a form of para-crystalline carbon of high surface area. Although activated carbon has a more favorable surface area to volume ratio (>1000 m 2 /g) than carbon black, its low electrical conductivity makes it unsuitable as electrode material. Commercial carbon blacks, such as Vulcan or Ketjen black have been most frequently used as support to ensure large electrochemical reaction surfaces and to reduce noble metal loading. Metal and Metal-Derived Particles Supported on Carbon BlackCO 2 ER can be carried out in gas phase, where gaseous CO 2 is fed to the cathode through gas diffusion electrodes (GDE), or in liquid phase, where CO 2 dissolved in the liquid electrolyte contacts the electrode. Figure 1 presents a schematic diagram of two possible configurations of both operation modes.C 2019, 5, x FOR PEER REVIEW 2 of 25 discussed, having in mind a commercial application.
