Abstract

Graphene with high-density defects was generated by one-step gaseous detonation method, designated as DG. The DG exhibits a highly hydrogen evolution reaction (HER) performance in terms of its lower onset potential of 223 mV and smaller Tafel slope of 120 mV·dec⁻¹, which are superior to those of commercial counterpart (CG). Furthermore, the value of DG acted as an excellent support of active materials was verified by successfully hybridizing the MoS₂ with DG and the improvement of DG on the HER performance of MoS₂. This work provides a simple, economical, energy-saving and high yield to prepared DG with highly HER electrocatalytic activity and advantages as an excellent support material, making it of great value in practical applications.

利用爆破法合成石墨烯的氢气进化反应性能研究

通过一步气态引爆法生成了具有高密度缺陷的石墨烯，命名为 DG。DG 具有较低的起始电位（223 mV）和较小的塔菲尔斜率（120 mV-dec-1），其氢进化反应（HER）性能优于商用石墨烯（CG）。此外，通过将 MoS2 与 DG 成功杂化，以及 DG 对 MoS2 HER 性能的改善，验证了 DG 作为活性材料优良支撑的价值。这项工作提供了一种简单、经济、节能和高产率的制备 DG 的方法，它具有很高的 HER 电催化活性和作为优良支撑材料的优势，使其在实际应用中具有重要价值。

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.
