Oxygen-deficient MoO/NiS heterostructure grown on nickel foam as efficient and durable self-supported electrocatalysts for hydrogen evolution reaction

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 4,   Pages 437-448 doi: 10.1007/s11705-022-2228-1

Abstract: High-performance and ultra-durable electrocatalysts are vital for hydrogen evolution reaction (HER) during water splitting. Herein, by one-pot solvothermal method, MoOx/Ni3S2 spheres comprising Ni3S2 nanoparticles inside and oxygen-deficient amorphous MoOx outside in situ grow on Ni foam (NF), to assembly the heterostructure composites of MoOx/Ni3S2/NF. By adjusting volume ratio of the solvents of ethanol to water, the optimized MoOx/Ni3S2/NF-11 exhibits the best HER performance, requiring an extremely low overpotential of 76 mV to achieve the current density of 10 mA∙cm‒2 (η10 = 76 mV) and an ultra-small Tafel slope of 46 mV∙dec‒1 in 0.5 mol∙L‒1 H2SO4. More importantly, the catalyst shows prominent high catalytic stability for HER (> 100 h). The acid-resistant MoOx wraps the inside Ni3S2/NF to ensure the high stability of the catalyst under acidic conditions. Density functional theory calculations confirm that the existing oxygen vacancy and MoOx/Ni3S2 heterostructure are both beneficial to the reduced Gibbs free energy of hydrogen adsorption (|∆GH*|) over Mo sites, which act as main active sites. The heterostructure effectively decreases the formation energy of O vacancy, leading to surface reconstruction of the catalyst, further improving HER performance. The MoOx/Ni3S2/NF is promising to serve as a highly effective and durable electrocatalyst toward HER.

Enhanced methanation stability of nano-sized MoS

Zhenhua LI, Jia HE, Haiyang WANG, Baowei WANG, Xinbin MA

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 1,   Pages 33-39 doi: 10.1007/s11705-014-1446-6

Abstract: A series of unsupported MoS catalysts with or without Al O modification was prepared using a modified thermal decomposition approach. The catalysts were tested for the methanation of carbon monoxide and the optimum one has 25.6 wt-% Al O content. The catalysts were characterized by nitrogen adsorption measurement, X-ray diffraction and transmission electron microscopy. The results show that adding appropriate amount of Al O increases the dispersion of MoS , and the increased interaction force between MoS and Al O can inhibit the sintering of active MoS to some extent.
