The development of high-kinetic catalysts for the hydrogen evolution reaction (HER) in a neutral electrolyte is of great importance but unfortunately remains a challenge so far. Herein, we report hybrids with abundant Ru-S-Sb bonds and engineered ultrathin antimonene (Ru-S-Sb/antimonene) as highly kinetic, active, stable electrocatalysts for the HER in an aqueous neutral electrolyte. Experiments and density functional theory (DFT) calculations reveal that Ru-S-Sb bonds coupling with antimonene synergistically work to promote HER activity. The present study brings us one step closer to understand the structure-composition-property relationships and practical electrolytic H2 production.
发展中性电解质中析氢反应 (HER) 的高动力学催化剂非常重要，但迄今为止，这仍然是一个挑战。在此，我们报告了具有丰富 Ru-S-Sb 键和工程化超薄碲化锑 (Ru-S-Sb/碲化锑) 的混合物，它们作为在水中性电解质中具有高动力学、活性和稳定性的 HER 电催化剂。实验和密度泛函理论 (DFT) 计算表明，Ru-S-Sb 键与碲化锑耦合协同作用，促进了 HER 活性。本研究使我们更进一步地理解了结构-组成-性能关系和实际的电解制氢。
