Mxene-Supported Co3o4 Quantum Dots For Superior Lithium Storage And Oxygen Evolution Activities

A novel hybrid, composed of Co3O4 quantum dots supported on Ti3C2Tx (MXene) nanosheets, exhibits a strong synergetic effect, and shows superior lithium storage (capacity = 766.5 mA h g(-1) at 2 A g(-1) after 400 cycles) and oxygen evolution (overpotential = 340 mV at 10 mA cm(-2)) activities.
