One-step hydrothermal synthesis of porous Ti3C2Tz MXene/rGO gels for supercapacitor applications

Sanjit Saha et al.

Summary: Titanium carbide/reduced graphene oxide (Ti3C2Tz/rGO) gels were prepared via a one-step hydrothermal process, exhibiting a highly porous structure with a high specific surface area. By adjusting the content of graphene oxide (GO) and Ti3C2Tz nanosheets in the precursor, different microstructures can be achieved. The gel electrodes showed enhanced supercapacitor performance due to the synergistic effect of EDLC from graphene oxide and redox capacitance from titanium carbide.
