Two-dimensional nano-MoS(2) holds remarkable potential for widespread use in hydrogen evolution reaction (HER) applications owing to its high catalytic activity, abundant availability, and low cost. However, its electrocatalytic performance is significantly lower than that of Pt-based catalysts necessitating strategies to improve its catalytic activity. We developed an effective strategy for enhancing the HER performance of MoS(2) based on the synergistic effect of oxygen vacancies (O(v)), heterostructures, and interfacial wettability. In particular, highly graphitized wood-based carbon (GWC) ...
