Abstract

This review provides a comprehensive analysis of the latest development of hydrogen (H₂)-selective metallic membranes for pre-combustion carbon dioxide (CO₂) capture. Highlighting the essential role of these membranes in CO₂ capture and storage technologies, we detail the membrane performance through the measurement of H₂ permeability under different operating conditions (i.e., temperature and pressure). Our assessments cover the advancement in alloy compositions, surface treatments, and manufacturing techniques to achieve improved membrane performance. Apart from this, in this review, we discuss the challenges encountered in fabricating metallic membranes, such as embrittlement, sulfur contamination, and high production costs, while suggesting potential solutions to these issues. Last but not least, future research direction for metallic membranes is proposed to emphasize the important strategies in developing these membranes in a scalable and cost-effective manner.

用于燃烧前二氧化碳捕获的 H2 选择性金属膜的进展：重要综述

本综述全面分析了用于燃烧前二氧化碳（CO2）捕集的氢（H2）选择性金属膜的最新发展。我们强调了这些膜在二氧化碳捕获和储存技术中的重要作用，并通过测量不同操作条件（即温度和压力）下的氢气渗透性详细介绍了膜的性能。我们的评估涵盖了合金成分、表面处理和制造技术的进步，以提高膜的性能。除此之外，在本综述中，我们还讨论了在制造金属膜时遇到的挑战，如脆性、硫污染和高生产成本，同时提出了解决这些问题的潜在方案。最后但并非最不重要的一点是，我们提出了金属膜的未来研究方向，以强调以可扩展和具有成本效益的方式开发这些膜的重要战略。
