A High-Efficiency Electrocatalyst for Oxidizing Glucose: Ultrathin Nanosheet Co-Based Organic Framework Assemblies

The glucose oxidation reaction (GOR) relies on noble metals (such as Au and Ag) and metal oxides (such as CuO, RuO2, and IrO2) as catalysts in a general way. However, these metal-based candidate materials often suffer from a variety of defects, including high cost, complexity of their synthesis method, and damage to the environment. Here, we synthesized ultrathin two-dimensional (2D) nanosheets (about 2.041 nm in thickness) that have a large surface area and good electrocatalytic properties for GOR The destination product was prepared using a one-step solvothermal process involving Co (NO3)(2)center dot 6H(2)O and p-phthalic acid synthesized in the presence of DMF/C2H5OH solution. The as-synthesized ultrathin 2D nanosheet Co-MOFs exhibited an electrocatalytic performance for the glucose that was better than that for the shell-like multilayer assemblies Co-MOFs in the alkaline electrolyte, including a higher stability, higher sensitivity, and better activity.
