CO₂ Capture at Medium to High Temperature Using Solid Oxide-Based Sorbents: Fundamental Aspects, Mechanistic Insights, and Recent Advances

Chemical Reviews, Год журнала: 2021, Номер 121(20), С. 12681 - 12745

Опубликована: Авг. 5, 2021

Carbon dioxide capture and mitigation form a key part of the technological response to combat climate change reduce CO2 emissions. Solid materials capable reversibly absorbing have been focus intense research for past two decades, with promising stability low energy costs implement operate compared more widely used liquid amines. In this review, we explore fundamental aspects underpinning solid sorbents based on alkali alkaline earth metal oxides operating at medium high temperature: how their structure, chemical composition, morphology impact performance long-term use. Various optimization strategies are outlined improve upon most materials, combine recent advances across disparate scientific disciplines, including discovery, synthesis, in situ characterization, present coherent understanding mechanisms absorption both surfaces within materials.

Electrolyte Oxidation Pathways in Lithium-Ion Batteries

Journal of the American Chemical Society, Год журнала: 2020, Номер 142(35), С. 15058 - 15074

The mitigation of decomposition reactions lithium-ion battery electrolyte solutions is critical importance in controlling device lifetime and performance. However, due to the complexity system, exacerbated by diverse set compositions, electrode materials, operating parameters, a clear understanding key chemical mechanisms remains elusive. In this work, operando pressure measurements, solution NMR, electrochemical methods were combined study oxidation reduction at multiple cell voltages. Two-compartment LiCoO2/Li cells cycled with conducting glass-ceramic separator so that species formed each could be identified separately further these opposite prevented. One principal finding (with an onset voltage ∼4.7 V vs Li/Li+ for LiCoO2), rather than reaction, dominant process positive surface system. This ascribed well-known release reactive oxygen higher states-of-charge, indicating are intrinsically linked reactivity active material. Soluble products both electrodes characterized, detailed reaction scheme constructed rationalize formation observed species. insights on through work have direct impact mitigating degradation high-voltage/higher-energy-density LiCoO2-based cells, more generally containing nickel-containing cathode materials (e.g., LiNixMnyCozO2; NMCs), as they lose lower

Опубликована: Янв. 3, 2023

Direct air capture (DAC) is gathering momentum since it has vast potential and high flexibility to collect CO2 from discrete sources as "synthetic tree" when compared with current technologies, e.g., amine based post-combustion capture. It considered one of the emerging carbon technologies in recent decades remains a prototype investigation stage many technical challenges be overcome. The objective this paper comprehensively discuss state-of-the-art DAC utilization, note unresolved technology bottlenecks, give perspectives for commercial large-scale applications. Firstly, characteristics physical chemical sorbents are evaluated. Then, representative processes, pressure swing adsorption, temperature adsorption other ongoing absorption loops, described compared. Methods conversion including synthesis fuels chemicals well biological utilization reviewed. Finally, techno-economic analysis life cycle assessment application summarized. Based on research achievements, future presented, which include providing guidelines obtaining desired characteristics, uncovering mechanisms different working processes establishing evaluation criteria terms economic aspects.

Abstract Capture and conversion of CO 2 from oceanwater can lead to net-negative emissions provide carbon source for synthetic fuels chemical feedstocks at the gigaton per year scale. Here, we report a direct coupled, proof-of-concept electrochemical system that uses bipolar membrane electrodialysis (BPMED) cell vapor-fed reduction (CO R) capture convert oceanwater. The BPMED replaces commonly used water-splitting reaction with one-electron, reversible redox couples electrodes demonstrates ability an energy consumption 155.4 kJ mol −1 or 0.98 kWh kg efficiency 71%. R yields total Faradaic up 95% CO. provides unique technological pathway only processes.
