二維層狀MXenes及生質碳材孔洞材料於電化學儲能系統暨催化之應用(3/3)

Two-dimensional layered MXenes have received increasing attention in recentyears due to their attractive properties and hold promise for applications fromenergy storage devices to catalysis. Although regulation of the surfacetermination, including the type and composition, can further optimize theelectrochemical performance of MXenes, the detailed interaction mechanismshave not fully understood yet. A better understanding of the reaction mechanismis vital to provide valuable information for the design and optimization of MXenebased electrodes. It is anticipated that manipulating the surface chemistry byreduction, oxidization, and surface modifications can be effective routes for tuningthe catalytic performance of MXenes. In addition, biomass-derived materials haveshown great success for LIB-negative electrodes, negative electrode sulfur hostfor Li-S batteries and for catalysis. The prospects of biomass derived carbonmaterials have improved remarkably over the past few years, but moreimprovements are still needed to exploit their full potentials for high-performanceenergy storage devices and in various catalytic reactions. Despite thecomprehensive study of graphene oxide (GO) and reduced GO (rGO) in energystorage and catalysis, more studies are needed on controlling the microstructuresof GO and rGO. Fundamental studies on the interaction mechanisms and thepotential synergistic effects between the GO/rGO and the additional material in acomposite should attract more interests for future energy storage and catalysisapplications. There is a tremendous opportunity to use different nanoparticles insingle or bimetallic forms incorporated in ordered mesoporous carbons modifiedwith different groups. Metals/metal oxides incorporated ordered mesoporouscarbons electrodes improve the capacity, rate capability and cycle life ofrechargeable batteries. CMK series mesoporous carbons, mainly, CMK-8 andCMK-9 and their functionalized forms are not fully studied in different batteryplatforms. There is a good scope of fabricating metal-metal oxide dopedOMCs/functionalized-OMCs electrodes with high capacity, rate capability andlonger cycle life.
