Abstract Scope |
MXenes are novel two-dimensional nanomaterials with outstanding properties, but their performance is limited by restacking when organized in three-dimensional (3D) configurations. To address this issue, we developed a fabrication method to create a composite structure with controlled electrical and electrochemical properties: MXene-infiltrated porous silica (MX-PS). The freeze casting method is utilized to fabricate a silica backbone with controlled porosity, followed by the infiltration of MXene dispersion to form a 3D network of thin-layer conformal coating. Through multiple infiltration cycles, a composite structure of MXene-infiltrated porous silica (MX-PS) with electrical conductivity reaching up to 340 S/m is fabricated. Using MX-PS composites as electrodes, the assembled sandwich-type supercapacitors demonstrate exceptional areal capacitance (7.24 F/cm²) and energy density (0.32 mWh/cm²) with just 6% additional mass from MXene. This study serves as proof of concept that integrating 2D nanomaterials into 3D porous structures can introduce new properties or enhance existing ones. |
