Title: Ultrafine Pt Nanoparticle-Decorated Pyrite-Type CoS 2 Nanosheet Arrays Coated on Carbon Cloth as a Bifunctional Electrode for Overall Water Splitting

Abstract

To improve the utilization efficiency of precious metals, metal-supported materials provide a direction for fabricating highly active and stable heterogeneous catalysts. Here, carbon cloth (CC)-supported Earth-abundant CoS2 nanosheet arrays (CoS2/CC) are presented as ideal substrates for ultrafine Pt deposition (Pt-CoS2/CC) to achieve remarkable performance toward the hydrogen and oxygen evolution reactions (HER/OER) in alkaline solutions. Notably, the Pt-CoS2/CC hybrid delivers an overpotential of 24 mV at 10 mA cm–2 and a mass activity of 3.89 A Ptmg–1, which is 4.7 times higher than that of commercial Pt/C, at an overpotential of 130 mV for catalyzing the HER. An alkali-electrolyzer using Pt-CoS2/CC as a bifunctional electrode enables a water-splitting current density of 10 mA cm–2 at a low voltage of 1.55 V and can sustain for more than 20 h, which is superior to that of the state-of-the-art Pt/C+RuO2 catalyst. Further experimental and theoretical simulation studies demonstrate that strong electronic interaction between Pt and CoS2 synergistically optimize hydrogen adsorption/desorption behaviors and facilitate the in situ generation of OER active species, enhancing the overall water-splitting performance. This research highlights the regulation of interfacial and electronic synergy in pursuit of highly efficient and durable supported catalysts for hydrogen and oxygen electrocatalytic applications.
