Research on the Electrocatalytic Hydrogen Evolution Performance of MoS2/NiSe2/CP Nano Composites
Two-dimensional layered molybdenum disulfide (MoS2) is a catalyst for hydrogen production by hydrogen evolution reaction (HER). However, it exhibits has poor electronic conductivity and a high activation energy barrier for adsorption/dissociation of water molecules in the alkaline HER, which limits its application in alkaline HER. In this paper, MoS2 was uniformly grown on three-dimensional conductive carbon paper (CP) by the hydrothermal method, presenting a nanoflower shape and effectively improving the conductivity of the electrode. Subsequently, NiSe2 was grown onto MoS2 nanoflowers in the form of nanoparticles by the secondary hydrothermal method to form a MoS2/NiSe2/CP nanocomposite structure. The structure and morphology of MoS2/NiSe2/CP were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed that MoS2 was composed of nanoflower-like structures formed by the combination of thin nanosheets. The average diameter of the nanoflowers is approximately 1.3 ± 0.2 μm. NiSe2 nanoparticles grew uniformly on the MoS2 nanoflowers, with an average particle size of 30–100 nm, providing a larger specific surface area that exposes more reactive sites. The MoS2/NiSe2 heterointerface is conducive to electron redistribution, and the XPS peak shifts Mo 3d: + 0.4 eV; S 2p: + 0.3 eV. The synergistic architecture provides an electrochemical surface area (ECSA) higher than that of MoS2/CP. The introduction of NiSe2 effectively inhibits the agglomeration of MoS2, enhances the dispersion of the catalyst on the substrate, and increases the effective reaction area. The MoS2/NiSe2/CP was tested for HER with an overpotential of only 112 mV at a current density of − 10 m cm−2 ang a Tafel slope of 42.01 mV dec⁻1. The introduction of NiSe2 nanoparticles effectively promoted the water adsorption/cracking reaction and thus co-catalyzed HER with MoS2, demonstrating good stability.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
