Review: harnessing engineered electrospun materials for efficient CO2 conversion into value-added products
摘要
One of the most pressing challenges of our time is carbon dioxide (CO2) reduction; though effective, traditional methods such as carbon capture and storage (CCS) and chemical absorption face significant scalability, cost, and energy efficiency limitations. Electrospun nanofibers (ENF) offer a promising alternative for effective CO2 conversion due to their high specific surface area, material versatility, and other tunable properties, enabling efficient CO2 conversion into value-added products such as methane, ethylene, and alcohol. This mini-review first presents the ENF overview and the advantages of CO2 reduction over traditional methods. Secondly, it presents case studies demonstrating the enhanced catalytic performance of electrospun materials, particularly nitrogen-doped carbon and hybrid metal oxide–carbon nanofibers, which have shown superior Faradaic efficiency and stability in CO2 reduction reactions. This mini-review also explores the limitations and challenges associated with scaling production, optimizing catalytic efficiency, and ensuring the durability of nanofibers in industrial applications. Finally, future opportunities for integrating electrospun materials with renewable energy systems and using artificial intelligence to optimize material design are discussed. Electrospun materials could play a pivotal role in advancing sustainable CO2 reduction technologies by addressing these challenges.
