Abstract
Polymer electrolyte membrane water electrolysis (PEMWE) is regarded as one of the most important cornerstone technologies in the upcoming hydrogen society. However, one of the major problems it encounters is its slow oxygen evolution kinetics, which necessitates the use of large amounts of precious metal catalysts to ensure a satisfactory reaction rate. Herein, we have prepared a series of RuOx with porous structures and ultrahigh Ru utilization toward the oxygen evolution reaction. All porous samples exhibit an enhanced catalytic performance compared with commercial RuOx. Particularly, for the RuOx-350 sample, the overpotential to reach 10 mA cm-2 is as low as 225 mV. It has obvious advantages among all reported pure RuO2-based catalysts. Here, a new strategy was raised to construct efficient RuO2 electrocatalysts with outstanding activity and stability for water electrolysis technology.

Abstract
![]()
The
stability of perovskite oxide catalysts for the oxygen
evolution
reaction (OER) plays a critical role in their applicability in water
splitting concepts. Decomposition of perovskite oxides under applied
potential is typically linked to cation leaching and amorphization
of the material. However, structural changes and phase transformations
at the catalyst surface were also shown to govern the activity of
several perovskite electrocatalysts under applied potential. Hence,
it is crucial for the rational design of durable perovskite catalysts
to understand the interplay between the formation of active surface
phases and stability limitations under OER conditions. In the present
study, we reveal a surface-dominated activation and deactivation mechanism
of the prominent electrocatalyst La0.6Sr0.4CoO3−δ under steady-state OER conditions. Using a
multiscale microscopy and spectroscopy approach, we identify the evolving
Co-oxyhydroxide as catalytically active surface species and La-hydroxide
as inactive species involved in the transient degradation behavior
of the catalyst. While the leaching of Sr results in the formation
of mixed surface phases, which can be considered as a part of the
active surface, the gradual depletion of Co from a self-assembled
active CoO(OH) phase and the relative enrichment of passivating La(OH)3 at the electrode surface result in the failure of the perovskite
catalyst under applied potential.

Abstract
The oxygen evolution reaction (OER) is one of the key kinetically limiting half reactions in electrochemical energy conversion. Model epitaxial catalysts have emerged as a platform to identify structure-function-relationships at the atomic level, a prerequisite to establish advanced catalyst design rules. Previous work identified an inverse relationship between activity and the stability of noble metal and oxide OER catalysts in both acidic and alkaline environments: The most active catalysts for the anodic OER are chemically unstable under reaction conditions leading to fast catalyst dissolution or amorphization, while the most stable catalysts lack sufficient activity. In this perspective, we discuss the role that epitaxial catalysts play in identifying this activity-stability-dilemma and introduce examples of how they can help overcome it. After a brief review of previously observed activity-stability-relationships, we will investigate the dependence of both activity and stability as a function of crystal facet. Our experiments reveal that the inverse relationship is not universal and does not hold for all perovskite oxides in the same manner. In fact, we find that facet-controlled epitaxial La0.6Sr0.4CoO3-δ catalysts follow the inverse relationship, while for LaNiO3-δ, the (111) facet is both the most active and the most stable. In addition, we show that both activity and stability can be enhanced simultaneously by moving from La-rich to Ni-rich termination layers. These examples show that the previously observed inverse activity-stability-relationship can be overcome for select materials and through careful control of the atomic arrangement at the solid-liquid interface. This realization re-opens the search for active and stable catalysts for water electrolysis that are made from earth-abundant elements. At the same time, these results showcase that additional stabilization via material design strategies will be required to induce a general departure from inverse stability-activity relationships among the transition metal oxide catalysts to ultimately grant access to the full range of available oxides for OER catalysis.

Abstract
Perovskite oxides have emerged as promising oxygen electrocatalysts for fuel cells and batteries, yet their catalytic activity and long-term stability are under debate because of local surface alterations and instabilities under sustained oxidative potential. Interconnected particles (40 nm) of Ba0.6Sr0.4Co0.79Fe0.21O2.67 (BSCF) are decorated by 10-50 wt % Ni0.6Fe0.4(OH)x [NiFe] layered double hydroxide (LDH) sheets via polyethylenimine linkage. This composite renders modulation of surface charges through Coulombic interaction and provides a leeway for electron mobility between the two components, which bestows relief to the BSCF surface from oxidative degradation. NiFe-LDH (25 wt %) bound to BSCF (BSCF/NiFe-25) is found to be the optimized bifunctional composite after considering the total overpotential of oxygen evolution and reduction reactions. With BSCF/NiFe-25 at the air electrode of a prototype-rechargeable Zn-air battery, a low discharge-charge voltage gap (1.16 V at 10 mA cm-2), unaltered cyclic stability over 100 h, and an energy density of 776.3 mW·h·gZn-1 are achieved. BSCF/NiFe-25 outperforms BSCF and is comparable to 20% Pt/C-RuO2 cathodes in all the standard figures of merit. Our work presents a general strategy to circumvent the reconstructions of perovskite oxide surface under oxidative potentials, by creating highly active, stable, and inexpensive bifunctional composite electrocatalysts for future electrochemical energy storage and conversion devices.
