“…Various strategies, such as morphology engineering, oxygen-vacancy control, phase structure engineering and non-metal or metal doping have been adopted to enhance the metal oxides electrocatalytic performance [4]. Besides of the metal oxides, metal chalcogenides and phosphides, such as MoS 2 [5], WSe 2 [6], CoP [7], MoP [8] and Ni 2 P [9], have generated great interest for their catalytic activity toward HER. Among them, two-dimensional (2D) MoS 2 has been investigated as the most potential alternative to Pt-based HER catalyst [10].…”

Electrocatalytic production of hydrogen from water is a promising and sustainable strategy. Herein, hierarchical tubular MoP/MoS2 composites with the wall composed of loosely stacked nanosheets were fabricated through partially phosphating the tubular MoS2. As an electrocatayst for hydrogen evolution reaction (HER), the hierarchical tubular MoP/MoS2 composite displayed a superior HER activity with a low overpotential (101 mV) to obtain a current density of 10 mA/cm2, small Tafel slope (56 mV/dec). Moreover, the MoP/MoS2 composite demonstrate superior long-term durability in acid electrolytes. The excellent catalytic activity of MoP/MoS2 composite may be ascribed to its hierarchical structure: hierarchical porous structure can offer mass diffusion pathways, and the nanosheets with MoP/MoS2 heterojunctions can provide rich active sites for HER. Density functional theory (DFT) calculations reveal that more favorable H* adsorption kinetics on the surface of the MoP/MoS2 composite during the HER process than pristine MoP and MoS2. This work can offer a strategy to design high performance electrocatalysts for HER applications.

Molybdenum disulfide, as an electronic highly-adjustable catalysts material, tuning its electronic structure is crucial to enhance its intrinsic hydrogen evolution reaction (HER) activity. Nevertheless, there are yet huge challenges to the understanding and regulation of the surface electronic structure of molybdenum disulfide-based catalysts. Here we address these challenges by tuning its electronic structure of phase modulation synergistic with interfacial chemistry and defects from phosphorus or sulfur implantation, and we then successfully design and synthesize electrocatalysts with the multi-heterojunction interfaces (e.g., 1T0.81-MoS2@Ni2P), demonstrating superior HER activities and good stabilities with a small overpotentials of 38.9 and 98.5 mV at 10 mA/cm2, a low Tafel slopes of 41 and 42 mV/dec in acidic as well as alkaline surroundings, outperforming commercial Pt/C catalyst and other reported Mo-based catalysts. Theoretical calculation verified that the incorporation of metallic-phase and intrinsic HER-active Ni-based materials into molybdenum disulfide could effectively regulate its electronic structure for making the bandgap narrower. Additionally, reduced nickel possesses empty orbitals, which is helpful for additional H binding ability. All these factors can decrease Mo-H bond strength, greatly improving the HER catalytic activity of these materials.
