Abstract

MoS2 has emerged as an attractive electrocatalyst for hydrogen evolution reaction (HER) although its performance still needs to be further enhanced, especially in alkaline solution due to inferior ability for water dissociation. Herein, we discover that coupling water-dissociation-active FeOOH with MoS2 grown on Ni3S2 nanowire arrays to achieve a core-shell Ni3S2@MoS2/FeOOH heterostructure can not only significantly accelerate the HER of MoS2, but also appreciably promote the OER activity of the catalyst. Systematic investigations on Ni3S2@MoS2/FeOOH and a series of delicately designed control catalysts reveal that such synergistically enhanced electrocatalytic performance for both OER and H..
