제목 Controlled Selenium Infiltration of Cobalt Phosphide Arrays Derived from Metal-Organic Framework for Flexible Asymmetric Supercapacitors
초록 Various composite materials containing transitional metals with selenium (Se) have been widely studied, but the controlled selenium penetration in a cobalt phosphide array derived from 2D Co-MOF is the different approach of material design for energy storage applications. In this work, 2D Co-MOF arrays are successfully grown on an activated carbon fiber textile (ACFT) and converted into Sex@CPNA-ACFT through successive phosphidization and selenium infiltration processes under the optimized conditions. In the 3-electrode system, Se0.6@CPNA-ACFT shows specific capacity of ∼302 mAh g–1 and excellent cycling stability. The ASC based on Se0.6@CPNA-ACFT and FeS2@rGO-ECFT exhibits a maximum energy density of ∼70.6 Wh kg–1 and power density of 8.163 kW kg–1 with remarkable stability. This work provides a good example of the rational modification of a 2D Co-MOF into an efficient Se0.6@CPNA-ACFT electrode material for a high-performance ASC for supercapacitor applications.
