摘要
金属有机框架(MOFs)材料因其丰富的拓扑结构和有序的孔洞结构被广泛关注,近年来人们按照其不同的应用前景分别进行了综述。尽管金属中心与有机框架材料的结构及性能有着密切联系,目前针对某种特定中心金属的金属有机框架材料的梳理还较少。金属铋是唯一一种具有较大丰度、低毒性的绿色重金属元素,铋基金属有机框架(Bi-MOFs)也因此在MOFs中脱颖而出,并具有广泛的应用。由于铋盐易水解的特性,在水相中合成铋基金属有机框架材料一直是一个挑战,所以对于Bi-MOFs的开发仍然处于开始阶段。本文介绍了近年来有关Bi-MOFs常用的合成配体以及一般的合成方法,综述了Bi-MOFs在光、电催化等领域的研究进展及其在药物载体、气体吸附剂及电极材料方面的应用概况。对存在的问题进行总结并提出可能的解决方法,对未来研究和应用提出展望,以推动Bi-MOFs材料的进一步研究与运用。
Metal-organic frameworks(MOFs),featuring the ordered porous structure and abundant topology,have been widely concerned and thoroughly reviewed according to its application prospects in recent years.Although the metal center is critical to the structure and performance of MOFs,summaries of the MOFs with a specific central metal are still few at present.As the only heavy metal element with considerable abundance and low toxicity,bismuth-based metal-organic frameworks(Bi-MOFs)stand out among MOFs for its innocuousness and biocompatibility.It would be a significant direction to design legitimately,synthesize successfully,and exploit steadily the Bi-MOFs with rich structures in the current MOFs research.However,this specific type of MOFs is still in its infancy,which is limited by the flexible coordination environment and low solubility of Bi(Ⅲ)cation.The synthesis of Bi-MOFs in the aqueous solution has always been an enormous challenge resulting from the hydrolysis of the bismuth salt.Herein,this article reviews the common ligands and general synthesis methods of Bi-MOFs in recent years,focusing on its application in photocatalysis,electrocatalysis,drug carriers,gas adsorbents and electrode materials.By profusely discussing the mechanism and reaction rules in catalytic reactions,this review aims to provide rewarding references for similar catalytic reactions to improve reaction efficiency and save costs.In addition,to highlight the unique advantages of Bi-MOFs,we make detailed comparisons with traditional materials.Some expanded applications of energy storage(mainly cationic battery energy storage),adsorption separation(selective adsorption of anions and enrichment of energy gas),drug delivery(the encapsulation and release of specific drugs)are also supplemented.For consideration of existing research,our work puts forward a prospect for future pioneering research to stimulate the research progress of Bi-MOFs.
