金属有机框架用于一氧化碳氧化

Metal-organic Frameworks for CO Oxidation

鉴于一氧化碳(CO)氧化在基础研究、环境保护和实际应用中的重要性,人们对其进行了广泛的研究.金属有机骨架(MOFs)由于具有永久孔隙,结构多样且可调控,是一种很有前途的CO氧化催化剂.本文对近年来MOFs和MOF基催化剂用于CO氧化的研究进展进行了系统的总结,并根据催化剂活性物种/位点进行了简要的分类介绍.除了催化剂的化学结构,催化剂的负载量、制备方法和预处理技术以及反应温度等对催化性能的影响也在文中进行了讨论.最后,本综述对该研究领域进行了总结和展望.

Due to its importance in fundamental studies,environmental protection and practical applications,the oxidation of carbon monoxide(CO)is extensively investigated.Metal-organic frameworks(MOFs)which contain abundant active species/sites are promising catalysts for CO oxidation owing to their permanent porosi⁃ty,structural diversity and tunability.Herein,we wish to provide a systematic summary of recent progress in MOFs and MOF-based catalysts for CO oxidation.Active species/sites of the catalysts are briefly classified on account of their different active elements.In addition to pristine chemical structure,many variables related to the structure of the catalysts,such as loading weight,preparation&pre-treatment techniques and reaction temperature,have been proven to show great influence on the property and will be discussed here.Finally,the review covers a short conclusion and perspective in this filed.
