Summary: This study demonstrated the use of a silver and samarium-doped ceria (SDC) mixed ceramic and metal composite as a cathode for low-temperature solid oxide fuel cells (LT-SOFCs). The ratio between Ag and SDC, which can be adjusted by the co-sputtering process, was found to be crucial for catalytic reactions and enhanced triple phase boundary (TPB) density in the nanostructure. The Ag-SDC cermet cathode not only improved the performance of LT-SOFCs by decreasing polarization resistance, but also showed higher catalytic activity than platinum (Pt) due to the improved oxygen reduction reaction (ORR). It was discovered that even a small amount of Ag content was effective in increasing TPB density while preventing oxidation of the Ag surface.

Summary: The study investigates the incorporation of silicon into Ruddlesden-Popper La2NiO4+delta mixed conducting ceramics to improve chemical compatibility with lanthanum silicate-based solid electrolytes. Results show that silicon additions lead to segregation of secondary phases and suppress both electrical conductivity and oxygen-ionic transport in the ceramics. The preferential reactivity of silica with lanthanum oxide suggests a potential to enhance compatibility between solid electrolytes and electrodes through surface modifications.

Summary: High-voltage Li-rich layered oxide materials have high energy density and low cost, but their electrochemical performance deteriorates under high voltages due to detrimental reactions with free anions, unstable electrode interface, and limited Li+ kinetic process. A highly oxidation-resistant carbonate electrolyte incorporating LiDFOB and TMSPi additives is demonstrated to manipulate the solvation structure, promoting the desolvation process of Li+ and suppressing harmful species generation. The Li||LLO cells with dual additives exhibit excellent cycle stability and improved rate capability in a wide temperature range, indicating a promising strategy for long-cycle stability of layered cathode materials under high voltage and wide-temperature conditions.

Summary: The fuel cell is a device that converts the chemical energy of fuel into electricity through its three layers - anode/electrolyte/cathode. Different fuel cell types are determined by the electrolyte membranes. Currently, solid-state and ceramic electrolyte SOFC/PCFC and polymer-based PEMFC fuel cells are the focus of research. However, a new fuel cell concept using ceramic nanocomposites made of semiconductor-ionic material combinations shows promising potential to improve power density and make fuel cells more affordable and accessible.

Summary: Infiltration of sulfur into microporous carbon enables the use of carbonate-based electrolytes, forming a compact cathode electrolyte interface. The mechanism of sulfur conversion changes to a quasi-solid-state mechanism, resulting in a single sloping plateau of sulfur conversion. The narrow size of pores determines the sulfur maximum ratio within the carbon-sulfur composite. The confinement of sulfur in narrow pores affects its conversion into Li2S2/Li2S due to volumetric changes.

Summary: This paper discusses the degradation pathway of xylose in supercritical water and finds that phenols and arenes are difficult to be gasified while furans, organic acids, ketones, and alcohols can be easily gasified. Comparing with glucose and guaiacol, xylose is more easily gasified. The degradation of phenols and arenes is the key step in the supercritical water gasification of biomass model compounds.

Summary: The doping of exotic metal ions in photocatalysts can lead to surface defects and changes in bandgap, which are crucial for their photocatalytic performance. In this study, bandgap modulation of La2NiO4 photocatalysts was achieved through precise control of defect concentration and transition metal oxidation state via A-site and B-site doping. The effects of single-metal and co-doping with K+, Sr2+, Co2+, and Mn2+ on the photocatalytic activity of La2NiO4 were investigated. It was found that co-doping had a significant synergistic effect on the optical properties and photocatalytic activity of La2NiO4. All single-metal-doped La2NiO4 samples exhibited higher photocatalytic activity than the pristine counterpart. Furthermore, the Sr2+, Co2+ co-doped La2NiO4 showed the best properties and achieved a hydrogen production rate more than 29 times higher than pure La2NiO4. Analysis revealed that surface oxygen vacancies acted as active sites for efficient separation and migration of photo-generated carriers. The co-doped photocatalyst not only had a narrower bandgap but also a more favorable conduction band position for photoinduced electron reduction. Overall, this work provides a simple method for introducing oxygen defects and modulating bandgap in Ruddlesden-Popper structure through metal ion doping and contributes to the understanding of the structure-dependence of the photocatalytic performance of perovskite materials.
