A review of modulation strategies for improving the catalytic performance of transition metal sulfide self-supported electrodes for the hydrogen evolution reaction

“…99 A multicomponent 1T-MoS 2 /Co 3 S 4 /Ni 3 S 2 nano-array self-supported electrode was reported by Chen et al The abundant interfaces and defects among the multicomponents provided abundant active sites, and the strong interactions among different components optimized the electronic structure of the catalyst, which synergistically enhanced the catalytic activity of 1T-MoS 2 /Co 3 S 4 /Ni 3 S 2 for electrolytic water splitting. 100 Xiao et al pyrolyzed the bimetallic CuCo 2 S 4 to construct the S vacancy-rich heterostructure of Cu 1.96 S/Co 9 S 8 . DFT theoretical calculations demonstrated that the S vacancies and heterointerfaces in Cu 1.96 S/Co 9 S 8 were able to optimize the electronic structure of the catalyst and the adsorption of HER intermediates.…”

Recent Advances in Molybdenum Disulfide and Its Nanocomposites for Energy Applications: Challenges and Development

“…The nanoarray is able to achieve low overpotentials of only 50 and 240 mV at a current density of 10 mA cm −2 for HER and OER, respectively. Furthermore, the nanoarray displays remarkable stability, making it a reliable and long-lasting option for applications in various electrochemical devices [ 252 ]. The SnO 2 @MoS 2 heterostructures and the synergistic effects of MoS 2 and SnO 2 contributed to the improved catalytic activity in both HER and OER.…”

Recent progress of molybdenum carbide based electrocatalysts for electrocatalytic hydrogen evolution reaction

“…Molybdenum (Mo), an abundant transition metal on earth, has shown unique physical and chemical properties due to its abundant d electronics and adjustable d band centre. [15][16][17][18] Molybdenum-based materials such as molybdenum oxide (MoO 2 ), 19,20 molybdenum sulfide (MoS 2 ), 21,22 molybdenum nitride (MoN), 23,24 molybdenum carbide (Mo x C), 25,26 and molybdenum phosphide (MoP) 27,28 have been investigated as promising candidates for energy conversion. Among them, the carbides of Mo have a hydrogen adsorption free energy similar to that of Pt and are highly active over a wide pH range.…”
