摘要

气候变化带来的负面影响日益严重，其主要原因是大气中二氧化碳浓度的增加，这就要求采用先进技术从大气中提取二氧化碳。在此，我们回顾了胺功能化二氧化硅复合材料从大气中捕获二氧化碳的原理、机理、吸收剂标准、性能测定和制备技术。用于二氧化碳捕集的胺二氧化硅吸收剂的制备方法有浸渍法、化学制图法、杂化功能化法和原位聚合法。成本高、性能差和可扩展性实际上对大规模应用构成了挑战。

Atmospheric carbon dioxide capture by adsorption on amine-functionalized silica composites: a review

The rising negative effects of climate change are caused mainly by the increase of atmospheric carbon dioxide concentrations, calling for advanced technologies to extract carbon dioxide from atmospheric air. Here we review carbon dioxide capture from atmospheric air by amine-functionalized silica composites with emphasis on development principles, mechanisms, absorbent criteria, performance determination, and preparation techniques. Amine-silica absorbent preparation for carbon dioxide capture is done by impregnation, chemical graphting, hybrid functionalization, and in situ polymerization. High costs, poor performance, and scalability are actually posing challenges for large-scale deployment.

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
