Title: Influence of Heterointerfaces on the Kinetics of Oxygen Surface Exchange on Epitaxial La_1.85Sr_0.15CuO₄ Thin Films

Abstract

Considerable attention has been directed to understanding the influence of heterointerfaces between Ruddlesden–Popper (RP) phases and ABO3 perovskites on the kinetics of oxygen electrocatalysis at elevated temperatures. Here, we report the effect of heterointerfaces on the oxygen surface exchange kinetics by employing heteroepitaxial oxide thin films formed by decorating LaNiO3 (LNO) on La1.85Sr0.15CuO4 (LSCO) thin films. Regardless of LNO decoration, tensile in-plane strain on LSCO films does not change. The oxygen surface exchange coefficients (kchem) of LSCO films extracted from electrical conductivity relaxation curves significantly increase with partial decorations of LNO, whereas full LNO coverage leads to the reduction in the kchem of LSCO films. The activation energy for oxygen exchange in LSCO films significantly decreases with partial LNO decorations in contrast with the full coverage of LNO. Optical spectroscopy reveals the increased oxygen vacancies in the partially covered LSCO films relative to the undecorated LSCO film. We attribute the enhanced oxygen surface exchange kinetics of LSCO to the increased oxygen vacancies by creating the heterointerface between LSCO and LNO.

Strain control of oxygen kinetics in the Ruddlesden-Popper oxide La_1.85Sr_0.15CuO₄

Journal Article Meyer, Tricia L. ; Jacobs, Ryan ; Lee, Dongkyu ; ... - Nature Communications

Oxygen defect control has long been considered an important route to functionalizing complex oxide films. However, the nature of oxygen defects in thin films is often not investigated beyond basic redox chemistry. One of the model examples for oxygen-defect studies is the layered Ruddlesden-Popper phase La2-xSrxCuO4-delta (LSCO), in which the superconducting transition temperature is highly sensitive to epitaxial strain. However, previous observations of strain-superconductivity coupling in LSCO thin films were mainly understood in terms of elastic contributions to mechanical buckling, with minimal consideration of kinetic or thermodynamic factors.

Journal Article Lee, Dongkyu ; Lee, Yueh-Lin ; Hong, Wesley T. ; ... - Journal of Materials Chemistry. A

Heterostructured oxide interfaces created by decorating Ruddlesden-Popper phases (A2BO4) or perovskites on perovskites have shown not only pronounced cation segregation at the interface and in the A2BO4 structure but also much enhanced kinetics for oxygen electrocatalysis at elevated temperatures. In this study, we report and compare the time-dependent surface exchange kinetics and stability of (La_0.5Sr_0.5)₂CoO₄ -decorated (LSC₂₁₄) La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF₁₁₃) and La_0.8Sr_0.2CoO_3-δ (LSC₁₁₃) thin films. While LSC₂₁₄ decoration on LSC₁₁₃greatly reduced the degradation in the surface exchange kinetics as a function of time relative to LSC₁₁₃, LSCF₁₁₃ with LSC₂₁₄ coverage showed comparable surface exchange kinetics and stability to LSCF₁₁₃.

Enhanced surface exchange activity and electrode performance of (La_2–2xSr_2x)(Ni_1–xMn_x)O_4+δ cathode for intermediate temperature solid oxide fuel cells

Journal Article Li, Wenyuan ; Guan, Bo ; Yan, Jianhua ; ... - Journal of Power Sources

Surface exchange kinetics of Ruddlesden-Popper (R-P) phase lanthanum nickelates upon Mn doping as an intermediate temperature solid oxide fuel cells (IT-SOFCs) cathode is investigated for the first time in this communication. To promote the exchange rate in oxygen reduction reaction (ORR) on nickelates, Mn is partially substituted for Ni. The oxygen exchange resistance is accurately measured by electrochemical impedance spectroscopy (EIS) with dense thin layer cathode. It is found that Mn substantially promotes the surface kinetics; a surface exchange coefficient (k) of 1.57 × 10^–6 cm/s is obtained at 700 °C for La_1.8Sr_0.2Ni_0.9Mn_0.1O_4+δ (Sr20Mn10), ~80% higher than that of themore »« less

High-Temperature 2D Optical Relaxation Visualizes Enhanced Oxygen Exchange Kinetics at Metal-Mixed Conducting Oxide Interfaces

Journal Article Skiba, Emily J. ; Perry, Nicola H. - ACS Applied Materials and Interfaces

Solid-state heterointerfaces are of interest for emergent local behavior that is distinct from either bulk parent compound. One technologically relevant example is the case of mixed ionic/electronic conductor (MIEC)–metal interfaces, which play an important role in electrochemistry. Metal–MIEC composite electrodes can demonstrate improved catalytic activity vs single-phase MIECs, improving fuel cell efficiency. Similarly, MIEC surface reaction kinetics are often evaluated using techniques that place metal current collectors in contact with the surface under evaluation, potentially altering the response vs the native surface. Here, techniques enabling direct and local in situ observation of the behavior at and around such heterointerfaces aremore »« less

Cation and anion topotactic transformations in cobaltite thin films leading to Ruddlesden-Popper phases.

Journal Article Chiu, I-Ting ; Lee, Min-Han ; Cheng, Shaobo ; ... - Physical Review Materials

Topotactic transformations involve structural changes between related crystal structures due to a loss or gain of material while retaining a crystallographic relationship. The perovskite oxide La0.7Sr0.3CoO3 (LSCO) is an ideal system for investigating phase transformations due to its high oxygen vacancy conductivity, relatively low oxygen vacancy formation energy, and strong coupling of the magnetic and electronic properties to the oxygen stoichiometry. While the transition between cobaltite perovskite and brownmillerite (BM) phases has been widely reported, further reduction beyond the BM phase lacks systematic studies. In this paper, we study the evolution of the physical properties of LSCO thin films uponmore »« less
