Abstract

Abstract: Hydrogen sulfide, usually considered to be an anode catalyst poison, strongly promotes methane oxidation over sulfur resistant catalysts. The role of H2S in oxidation of sour CH4 feed over a sulfur resistant SOFC anode catalyst at 850°C has been determined through thermodynamic and experimental studies. The anode material was an intimately mixed 50/50 mass ratio composite of La0.4Sr0.6TiO3−δ and YSZ. The power density improved dramatically from 2mWcm−2 with pure CH4 as fuel to more than 450mWcm−2 for CH4 containing 20% H2S. However, H2S was not the only fuel converted, and its interaction with CH4 was the key factor in enhancement of performance. The anode effluent gas mixture included H2S, SO2, H2 and CS2 consistent with thermodynamic predictions. The role of H2S in the CH4 oxidation mechanism was determined, and showed that CH4 and H2S must be considered together as a fuel and not as two separate fuels. The types of electrochemical reactions that occurred in the fuel cell were strongly dependent on potential. [Copyright &y& Elsevier]

Abstract

Designing anodic electrocatalysts with high activity and robust stability for acidic oxygen evolution reaction (OER) is significant for the large-scale promotion of sustainable proton exchange membrane water electrolysis (PEMWE). Most reported Ru-based electrocatalysts tend to further improve activity at the expense of stability. Herein, we report the synthesis of crystalline Mn 3 O 4 supported Ru-RuO 2 nano-heterostructures as the anodic electrocatalyst that only requires a low overpotential of 182 mV (10 mA cm−2) for acidic OER, accompanied with a record stability of 400 h in 0.5 M H 2 SO 4. The results of XPS, ICP-MS, and XAS indicate that the Mn 3 O 4 substrate plays a crucial role in stabilizing Ru-RuO 2 nano-heterostructure by preventing Ru from over-oxidation and dissolution. Meanwhile, DEMS with isotope labeling reveals that the Ru-RuO 2 nano-heterostructure contributes to suppressing lattice oxygen oxidation mechanism (LOM) and concurrently expediting the involvement of adsorbate evolution mechanism (AEM) for boosting the acidic OER performance. [Display omitted] • The constructed Ru-RuO 2 /Mn 3 O 4 /CP only requires a low overpotential of 182 mV (10 mA cm−2) in 0.5 M H 2 SO 4. • Long-term stable acidic oxygen evolution reaction (400 h) is achieved in a membrane-free electrolyzer. • Experimental studies demonstrate that the Mn 3 O 4 substrate can protect Ru sites from over-oxidation and dissolution. • The modulation of OER pathways is deeply investigated by the experimental and calculation results. • It successfully brings about an effective strategy to maintain active Ru sites on the Mn 3 O 4 substrate.
