Two-dimensional (2D) layered double hydroxides (LDHs) are promising as an effective electrocatalyst towards oxygen evolution reaction (OER), but their poor conductivity and tendency to stack together limits activity durability electrocatalyst. Herein, a three-dimensional (3D) core–shell catalyst, in which numerous LDH nanoplates vertically grown on cuboidal metal organic framework (MOF) structures, is synthesized through facile one-pot strategy. The representative (CoNi-BDC@LDH) achieves...
Fe2B is a potentially promising electrocatalyst for the oxygen evolution reaction (OER) due to its excellent electronic conductivity, which superior that of traditional oxide catalysts. However, activity still not satisfactory. In this study, meta-stable microstructure stacking faults (SFs) were incorporated into through one-step high-pressure and high-temperature (HPHT) method. Pressure suppressed atomic diffusion but formed SFs when grain grew. with exhibited remarkable OER activity, low...
The construction of high-performance catalysts for overall water splitting (OWS) is crucial. Nickel–iron-layered double hydroxide (NiFe LDH) a promising catalyst OWS. However, the slow kinetics HER under alkaline conditions seriously hinder application NiFe LDH in This work presents strategy to optimize OWS performance by adjusting entropy multi-metallic LDH. Quaternary NiFeCrCo was constructed, which exhibited remarkable activity. OER and were stable 100 h 80 h, respectively. activity...

The oxygen evolution reaction (OER) is a significant contributor to the cell overpotential in solid oxide electrolyzer cells (SOECs). Although noble metals such as Ru and Ir have been utilized OER catalysts, their widespread application SOECs hindered by high cost limited availability. In this study, we present highly effective approach enhance air electrode performance durability depositing an ultrathin layer of metallic Ru, thin ∼7.5 Å, onto (La0.6Sr0.4)0.95Co0.2Fe0.8O3-δ (LSCF) using...
In this report, we demonstrate how a uniform angstrom-level oxide overcoat (0.7–1.5 Å) by atomic layer deposition is highly effective not only in enhancing the thermal stability of underlying infiltrated ceria nanoparticles but also facilitating electrode kinetics.
In this study, the impact of various infiltrates on kinetics and rate-limiting step oxygen reduction reaction (ORR) is examined with LaNi0.6Fe0.4O3- δ (LNF) as cathode backbone a solid oxide fuel cells (SOFC). Five materials were infiltrated: LaNi1-xFexO3- δ, LaxSr1-xCoyFe1-yO3-δ (LSCF), La1-xSrxMnO3-δ (LSM), Gd1-xCexO2-δ (GDC) Pr6O11. The dependence electrode polarization resistance precursor concentration, temperature, partial pressure presented related discussions ORR rate-determining for...
Long-term durability of perovskite (ABO3)-based cathodes in solid oxide fuel cells has been largely limited by surface segregation A-site dopant and thermal agglomeration. Since a deposition an atomically thin proven to be highly effective suppressing electrode agglomeration, successful suppression with the same approach will enhance significantly killing two birds one stone. In this report, we demonstrate that atomic-scale overcoat nominal thickness 2–3 Å is indeed tuning Sr behavior...
The development of non-precious metal electrocatalysts with remarkable activity is a major objective for achieving high-efficiency hydrogen generation. Here, trimetallic electrocatalyst dendritic nanostructure, which denoted as NiMoCu-NF, was fabricated on nickel foam via gas-template electrodeposition strategy. By virtue the metallic doping and structural optimization, NiMoCu-NF exhibits superior HER electrocatalytic an overpotential 52 mV at 10 mA cm-2. Additionally, NiMoCu-NF-derived...
Reversible solid oxide cells (rSOCs), which can operate both in fuel cell and electrolysis modes, offer an effective solution for the conversion storage of renewable energy with hydrogen as carrier. Nonetheless, commercialization rSOCs remains limited due to technical challenges such yet insufficient electrochemical performance (particularly intermediate temperature range 500-700 °C), short lifespan caused by degradation phenomena, high system costs associated operating temperatures. rSOCs,...
