摘要
Wood, becoming a renewable biomass resource, shows a lot of potential for various uses. In this work, we developed a novel carbonized wood as a substrate material, and AgCo-MOF/MnS was deposited on it. This composite material AgCo-MOF/MnS@CWS possesses unique properties such as excellent specific capacitance, adaptability, flexibility, and the capacity to produce high electrical power. When tested in a three-cell assembly, the resultant composite showed remarkable performance by delivering a specific capacity of 1068 C/g at 1.0 A/g. A supercapacitor was also built by merging AgCoMOF/MnS@CWS and AC@CWS in a two-cell configuration. The energy and power density for the AgCoMOF/MnS@CWS//AC@CWS device was 50 Wh/kg and 830 W/kg, respectively. Additionally, the stability measurement indicates that AgCoMOF/MnS@CWS//AC@CWS can retain up to 98% of its initial capacity after 12000 GCD cycles. The AgCo-MOF/MnS demonstrates a 146 mV overpotential along a 45 mV/dec Tafel slope in the OER application.
