摘要

本研究以M:Ni:HDA配合物（M = MoO3, Nb2O5, V2O5, WO3, HDA =十六胺）为原料，在氮气存在下，通过固相反应在高温下合成了过渡金属碳化物纳米管，包括碳化钼（β-Mo2C）、碳化铌（Nb6C5）、碳化钒（V6C5）和碳化钨（WC）。采用粉末x射线衍射（PXRD）、拉曼光谱（Raman spectroscopy）、x射线光电子能谱（XPS）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）等多种技术表征了这些金属碳化物纳米管的结构、化学成分和形貌。讨论了这些纳米管形成的生长机制。此外，我们还评估了这些纳米管的析氢反应（HER）活性。

A Facile Synthetic Route to Transition Metal Carbide Nanotubes with Enhanced Electrocatalytic Activity for the Hydrogen Evolution Reactions

In this study, transition metal carbide nanotubes, including molybdenum carbide (β-Mo₂C), niobium carbide (Nb₆C₅), vanadium carbide (V₆C₅), and tungsten carbide (WC), were synthesized from a complex of M:Ni:HDA (where M = MoO₃, Nb₂O₅, V₂O₅, WO₃ and HDA = hexadecylamine) in the presence of nitrogen gas at high temperatures through a solid-state reaction. Various techniques were employed to characterize the structure, chemical composition, and morphology of these metal carbide nanotubes, including powder X-ray diffraction (PXRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The growth mechanism involves in the formation of these nanotubes is discussed. Furthermore, we evaluated the hydrogen evolution reaction (HER) activities of these nanotubes.

期刊介绍： The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
