The hydrogen evolution reaction (HER) in the renewable energy system has gained a lot of attention from researchers as is assumed to be clean and carrier. Transition metals their compounds have been used promising alternatives precious noble for HER, offering low cost, more availability, high activity. In this work, we discussed mechanisms HER how morphology influenced catalytic performance transition metal disulfide (TMD), focusing on structures that range zero-dimensional (0D) three-dimensional (3D) TMD materials. Notably, two-dimensional (2D) TMDs, like nanosheets, exhibit lowest overpotential very small Tafel slope, which can ascribed inherent layered structure large surface area. According recent research reports, efficacy efficiency process are by chemistry, electrochemical characteristics, existence active sites.

Tungsten disulfide (WS2), a promising electrocatalyst made from readily available materials, demonstrates significant effectiveness in the hydrogen-evolution reaction (HER). The study conducts thorough investigation using various analytical methods such as scanning electron microscopy (SEM), transmission (TEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD), absorption spectroscopy (XAS), paramagnetic resonance (EPR), and situ Raman spectroscopy. These techniques have uncovered changes WS2 particle structure during HER. Through employing EPR, XAS, spectroscopy, research reveals structural chemical transformations. This includes formation of novel W species signs W–O bond formation. Moreover, morphology particles were observed. findings offer enhanced insights into mechanisms under HER conditions, highlighting its catalytic performance durability.
