One-step extended strategy for the ionic liquid-assisted synthesis of Ni3S4–MoS2 heterojunction electrodes for supercapacitors

A Ni₃S₄–MoS₂ heterojunction was successfully prepared with the assistance of an ionic liquid in one step, and it showed high performance as a supercapacitor electrode. This synthesis strategy can be applied to prepare other M_xS_y–MoS₂ heterojunctions.
