The catalytic properties of non-noble metal catalysts are not comparable to those of noble metal catalysts, such as Pt and Ru, on account of the catalytic thresholds of these non-noble metal catalysts. In order to solve this problem, an efficient P, W-MoS2/NiSP/NF catalyst was rationally designed through heteroatom (P and W) doping and heterostructure construction. Interestingly, motivated by the synergistic incorporation of W and P, the 2H-phase MoS2 with limited edge active sites was partially converted into highly active 1T-phase MoS2 with rich defects, which basically activate the hydrogen evolution reaction (HER)-inert basal plane of MoS2 and significantly enlarge the number of active sites, ultimately endowing the well-designed P, W-MoS2/NiSP/NF catalyst with Pt-like HER performance and superior oxygen evolution reaction (OER) performance. Importantly, this work exerts a profound influence on the construction of 1T-MoS2 with defects, the design of multi-stage structures, and the achievement of Pt-like catalytic performance.
