Abstract
Two-dimensional transition metal carbides (MXenes) were recently emerged as promising electrode materials for energy storage applications. Herein, we report a high-capacity supercapacitor material based on nitrogen-doped delaminated titanium carbides (N-d-Ti3C2) synthesized through the facile urea-assisted delamination of large-scale Ti3C2 and carbonization of delaminated Ti3C2 (d-Ti3C2) mixed with urea. The two-dimensional N-d-Ti3C2 nanosheets exhibit a high specific capacitance of 266.5Â FÂ gâ1 at the scan rate of 5Â mVÂ sâ1 in 6Â M KOH electrolyte solution, with a high capacitance retention capability. This new type of nitrogen-doped delaminated titanium carbide could be a promising electrode material for high-performance supercapacitors.
