Lithium-based ceramics in nonsilicates for CO2 capture: current status and new trends

Abstract

Carbon capture and storage (CCS) technology has been broadly recognized as having the potential to play a key role in mitigating the climate changes induced by enormous emissions of greenhouse gases, especially CO₂. Among various CO₂ sorbents, lithium-based ceramics in nonsilicates have been identified as promising candidates and have gained worldwide interest for CO₂ capture. With the rapid progress in these ceramic sorbents, a timely review is urgently required. Thus, in this work we review the current state-of-the-art research studies in the literature on lithium-based ceramics in nonsilicates for CO₂ capture. Recent advances in these lithium ceramics have been summarized in detail and discussed, including Li₂CuO₂, Li₅AlO₄, LiFeO₂/Li₅FeO₄, Li₆CoO₄, Li₄TiO₄/Li₂TiO₃, LiYO₂, Li₆WO₆/Li₄WO₅, Li₆ZnO₄, LiBO₂/Li₃BO₃, Li₇BiO₆, Li₅GaO₄, Li₅SbO₅, and Li₆MnO₄. The potential future development recommendations are also discussed. We hope that this work will benefit researchers from both academic and industrial communities and help pave the way for major breakthroughs in both fundamental research and industrial applications in this field.
