Abstract Sustainable hydrogen, produced from renewable sources such as solar or wind, plays a decisive role in driving industrial decarbonization. Among hydrogen production technologies, steam electrolysis, and solar‐driven thermochemical cycles using reducible solid oxides show promise but face challenges due to high operation temperatures. Microwave‐driven redox chemical looping enables the direct, contactless electrification of process, reducing temperature complexity. Previous works...
A robust LSM-GDC composite was used as a backbone electrode for the infiltration of different catalysts, dispersed oxide nanoparticles after firing.
Robust Ru nanoparticles created by exsolution enhanced the chemical looping methane reforming performance for stable syngas production and CO<sub>2</sub> splitting
Exsolution has emerged as a promising method for generating metallic nanoparticles, whose robustness and stability outperform those of more conventional deposition methods, such impregnation. In general, exsolution involves the migration transition metal cations, typically perovskites, under reducing conditions, leading to nucleation well-anchored nanoparticles on oxide surface with particular properties. There is growing interest in exploring alternative methods that do not rely...
New composite cathodes for proton conducting solid oxide fuel cells (PC-SOFCs) based on the novel La5.5WO12−δ (LWO) electrolyte have been developed.
