摘要
强烈的金属-载体相互作用诱导复合效应在催化反应中起着至关重要的作用。在此，我们揭示了MoSe2、Ru和锚定在二维有序MoSe2纳米片嵌入的中孔中空碳球表面（Ru/MoSe2@MHCS)用于大大提高的析氢反应（HER）性能。导电载体、亲氧MoSe2和Ru活性位点的组合优势赋予了Ru外围的强协同效应和电荷再分配，这诱导了HER的高催化活性、稳定性和动力学。具体而言，所获得的Ru/MoSe2@MHCS在酸性和碱性介质中分别需要25.5和38.4 mV的小过电位来驱动10 mA cm−2的动力学电流密度，这与Pt/C催化剂的过电位相当。实验和理论结果表明，从MoSe2到Ru NPs的电荷转移富集了Ru位点的电子密度，从而促进了氢的吸附和水的离解。目前的工作表明，界面工程在钌基催化剂的开发和通过金属-载体相互作用理解催化促进效果方面具有重要意义。
Electrochemical hydrogen evolution efficiently boosted by interfacial charge redistribution in Ru/MoSe2 embedded mesoporous hollow carbon spheres
The strong metal-support interaction inducing combined effect plays a crucial role in the catalysis reaction. Herein, we revealed that the combined advantages of MoSe2, Ru, and hollow carbon spheres in the form of Ru nanoparticles (NPs) anchored on a two-dimensionally ordered MoSe2 nanosheet-embedded mesoporous hollow carbon spheres surface (Ru/MoSe2@MHCS) for the largely boosted hydrogen evolution reaction (HER) performance. The combined advantages from the conductive support, oxyphilic MoSe2, and Ru active sites imparted a strong synergistic effect and charge redistribution in the Ru periphery which induced high catalytic activity, stability, and kinetics for HER. Specifically, the obtained Ru/MoSe2@MHCS required a small overpotential of 25.5 and 38.4 mV to drive the kinetic current density of 10 mA cm−2 both in acid and alkaline media, respectively, which was comparable to that of the Pt/C catalyst. Experimental and theoretical results demonstrated that the charge transfer from MoSe2 to Ru NPs enriched the electronic density of Ru sites and thus facilitated hydrogen adsorption and water dissociation. The current work showed the significant interfacial engineering in Ru-based catalysts development and catalysis promotion effect understanding via the metal-support interaction.
