Abstract Generation of hydrogen fuel via electrochemical water splitting powered by sustainable energy, such as wind or solar is an attractive path toward the future renewable energy landscape. However, current electrolysis requires desalinated resources, eventually leading to costs and scarcity. The development cost‐effective electrocatalysts capable saline feeds directly can be evident solution. Herein, a surface reconstructed nickel‐iron layered double hydroxide (NF‐LDH) reported...
Direct utilization of hydrocarbon and other renewable fuels is one the most important issues concerning solid oxide fuel cells (SOFCs). Mixed ionic electronic conductors (MIECs) have been explored as anode materials for direct hydrocarbon-type SOFCs. However, electrical conductivity often reported MIEC electrodes still not satisfactory. As a result, mixed-conducting oxides with high catalytic activity are attracting considerable interest an alternative material noncoke depositing anodes. In...
Compared to traditional deposition techniques, in situ growth of nanoparticles on material surfaces is one the more time- and cost-effective ways design new catalysts. The B-site transition-metal cations perovskite lattice could be partially exsolved as under reducing conditions, greatly enhancing catalytic activity. Here, we demonstrate that growing surface a layered La0.8Sr1.2Fe0.9Co0.1O4±δ (LSFC), which applied redox stable active electrode for intermediate-temperature symmetrical solid...

In all these applications, perovskite oxides, or derivatives offer highly competitive performance, often state art so tend to dominate research into material. following...
Abstract Robust oxide electrodes with high activity and durability have attracted significant attention as alternatives for Ni‐based cathodes in high‐temperature solid electrolysis cells (SOECs). Noncoking La(Sr)Cr(Mn)O 3 (LSCM)‐based shown promise durable ceramic cathodes; however, they suffer from low electrocatalytic activities electrochemical CO 2 reduction. In this study, a dual‐phase composite electrode consisting of LSCM Ce(Mn, Fe)O (CMF) is developed to enhance the reduction SOECs....
Protonic ceramic electrochemical cells (PCECs) have attracted considerable attention owing to their ability reversibly convert chemical fuels into electricity at low temperatures below 600 °C. However, extreme sintering conditions during conventional convection-based heating induce critical problems for PCECs such as nonstoichiometric electrolytes and microstructural coarsening of the electrodes, leading performance deterioration. Therefore, we fabricated via a microwave-assisted process...

The layered double perovskite, PrBaMn2O(5+δ), found to enhance electrocatalytic activity reduction on the side since it supports mixed valent transition metal cations such Mn, which could provide high electrical conductivity and maintain large oxygen vacancy content, contributing fast ion diffusion. It that during oxidation of reduced (O5 phase)...
