Nitrogen and sulfur co-doped carbon quantum dot-decorated Ti 3 C 2 T x -MXenes as electrode materials for high-performance symmetric supercapacitors

This work demonstrates a smartly engineered 0D/2D NS-CQD/MXene hybrid that unfolds rich redox activity, improved ion transport and pseudocapacitance by obstructing MXene restacking- paving the way for next generation supercapacitor applications.
