Description
Technical Field
The invention relates to the technical field of electrochemistry and nano materials, in particular to a preparation method and application of a Cu-Co-S-MOF nanosheet.
Background
The increasing consumption of fossil fuels and the emission of greenhouse gases have a great impact on the environment, resulting in a growing global demand for sustainable energy supplies. But only sustainable energy is insufficient, and the world needs to explore an efficient, stable and environment-friendly energy storage device to improve the energy storage efficiency. Super Capacitors (SC) have received a great deal of attention as an energy storage device with high power density, long cycle life, low cost, and fast charge and discharge time, and therefore, development and utilization of renewable clean energy sources are becoming more and more important.
Electrodes prepared by conventional slurry coating techniques have two disadvantages: on one hand, the surface area is small, so that the capacity performance is limited; another aspect is that the binder used can reduce the conductivity.
The metal organic framework has a unique crystal structure and chemical diversity, and is widely applied to the fields of water splitting, fuel cells, solar cells, lithium ion batteries, stem cells, sensors, biosensors and the like. Recently, much research has focused on the design and fabrication of MOFs with tunable morphologies. However, the design and fabrication of MOFs is not a practical, or cost-effective, method, which hinders their practical application in the commercial field. To achieve greater cost effectiveness, there is a need to simplify the design and fabrication of MOFs with high electrochemical performance. In recent years, a small amount of MOFs have been reported as the SCs electrode material, but their specific capacity and rate performance are relatively low, and the preparation method is only suitable for laboratory model, so that the industrial application cannot be implemented.
