Optimized trimetallic selenide heterostructures as high-performance trifunctional electrodes for self-sustained hydrogen production

One pot annealing is employed to synthesize N-doped trimetallic selenides. The trisellenide that consist of Ni 3 Se 2 , Co 0.85 Se, and MoSe 2 is used as higher performance trifunctional electrode material for supercapacitor, hydrogen and oxygen evolution reactions.
