Materials for Direct Air Capture and Integrated CO2 Conversion: Advancement, Challenges, and Prospects

Abstract

Direct air capture and integrated CO₂ conversion (DACC) technologies have emerged as promising approaches to mitigate the increasing concentration of carbon dioxide (CO₂) in the Earth’s atmosphere. This Perspective provides a comprehensive overview of recent advancements in materials for capturing and converting atmospheric CO₂. It highlights the crucial role of materials in achieving efficient and selective CO₂ capture as well as catalysts for CO₂ conversion. The paper discusses the performance, limitations, and prospects of various materials in the context of sustainable CO₂ mitigation strategies. Furthermore, it explores the multiple roles DACC can play in stabilizing atmospheric CO₂.
