The technology of electrolytic water splitting to produce hydrogen is considered a promising method for renewable energy utilization. It is essential to develop bifunctional electrode materials with low cost and high activity. Herein, tremella-like MoS2-AB particles on nickel foam substrate were fabricated through a one-step Solvothermal reaction and exhibited excellent electrocatalytic performance for over-water electrolysis in alkaline media, i.e., overpotentials of 77 and 248 mV to achieve catalytic current density 10 mA cm-2 for hydrogen evolution reaction and oxygen evolution reaction, respectively. Moreover, the two-electrode device demanded 1.51 V cell voltage to reach 10 mA cm-2 and showed good stability of 12 h without iR compensation. This work may afford a new idea to design self-supported bifunctional electrocatalysts toward efficient overall water splitting reactions.
