The electro-oxidation of alcohols into corresponding aldehydes achieved enormous attention. However, numerous challenges remain in exploring catalytic systems with high conversion efficiency and selectivity. Considering the worldwide attention toward metal-organic frameworks (MOFs) as outstanding crystalline porous materials, many chemists have been encouraged to use them in organic transformations. In this study, a novel coral-shaped cobalt organic framework was grown onto the surface of a functionalized graphite electrode (Co-MOF/C) to fabricate an efficient modified electrode in the electro-oxidation alcohols. The modified Co-MOF/C electrode showed high stability, large surface area, rich pores, and good conductivity as a desirable water-stable working electrode for selective oxidation of alcohols into aldehydes in good to excellent yields under a diffusion-controlled process.
醇的电氧化生成相应的醛受到了广泛关注。然而，在探索具有高转化效率和选择性的催化体系方面仍存在诸多挑战。鉴于金属有机框架（MOFs）作为出色的晶体多孔材料受到全球关注，许多化学家受到鼓舞将其用于有机转化。在本研究中，一种新型珊瑚状钴有机框架生长在功能化石墨电极（Co-MOF/C）表面，以制备用于醇电氧化的高效修饰电极。修饰后的Co-MOF/C电极表现出高稳定性、大表面积、丰富的孔隙以及良好的导电性，是一种理想的水稳定工作电极，可在扩散控制过程中将醇选择性氧化为醛，产率良好至优异。
