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

使用基于固体氧化物的吸附剂在中高温下捕获 CO2：基本方面、机理见解和最新进展

二氧化碳捕获和减缓是应对气候变化和减少 CO ₂排放的技术响应的关键部分。在过去的二十年里，能够可逆地吸收 CO ₂的固体材料一直是研究的重点，与更广泛使用的液体胺相比，它具有良好的稳定性和较低的实施和操作能源成本。在这篇综述中，我们探讨了支撑固体 CO _{2的基本方面}基于碱金属和碱土金属氧化物的吸附剂在中高温下运行：它们的结构、化学成分和形态如何影响其性能和长期使用。概述了各种优化策略以改进最有前途的材料，我们结合不同科学学科的最新进展，包括材料发现、合成和原位表征，以对表面和表面的 CO ₂吸收机制提出一致的理解。固体材料内。
