Recent Progress in Application of Porphyrin-based Metal-organic Framework Materials in Photocatalytic Reactions

金属卟啉有机框架材料是一种由卟啉或金属卟啉作为结构单元构筑的新型周期性网状结构材料,既具有卟啉拓宽光谱响应范围、降低光生电子-空穴复合率的独特优势,又具有MOFs(金属有机骨架)材料的多孔道、孔道尺寸可调节、比表面积大的优势,成为目前具有良好光电性质的新型光催化剂。近年来,许多科学家们致力于新型光催化剂的开发与应用。尤其是近几年来,随着材料科学的发展,新型光催化剂金属卟啉MOFs成为光催化剂的研究热点并取得了令人欣慰的成果。该文综述了近十年来卟啉/金属卟啉MOFs在二氧化碳还原、裂解水制氢、光降解有机染料等领域的最新应用,并对未来卟啉金属有机框架在光催化领域的发展进行了展望。

Porphyrin-based metal-organic framework materials(MOFs)as a new type of periodic reticular structure materials are composed of porphyrins or metal-based porphyrins as structural unit.Due to the unique advantages of porphyrins in expanding the spectral response range and reducing the recombination of photogenic electron-hole pairs,as well as the advantages of porosity,pore size adjustability and large specific surface area of MOFs,porphyrin-based MOFs have become a new type of photocatalyst with good photoelectric properties.In recent years,many scientists have been concerned on the development and application of porphyrin-based MOFs.Especially,the porphyrin-based MOFs as new photocatalyst become the research hotspot and obtains the gratifying results.In this paper,we mainly review the latest applications of porphyrin-based/metal-based porphyrin-based MOFs in the fields of carbon dioxide reduction,photocatalytic hydrogen production,photodegradation organic dyes.Finally,we present the future development of porphyrin-based MOFs in the field of photocatalysis.
