Alternative Strategy for Development of Dielectric Calcium Copper Titanate-Based Electrolytes for Low-Temperature Solid Oxide Fuel Cells.

The development of low-temperature solid oxide fuel cells (LT-SOFCs) is of significant importance for realizing the widespread application of SOFCs. This has stimulated a substantial materials research effort in developing high oxide-ion conductivity in the electrolyte layer of SOFCs. In this context, for the first time, a dielectric material, CaCuTiO (CCTO) is designed for LT-SOFCs electrolyte application in this study.

Hierarchical TiC/BiVO microcapsules for enhanced solar-driven water evaporation and photocatalytic H evolution.

Desalination processes frequently require a lot of energy to generate freshwater and energy, which depletes resources. Their reliance on each other creates tension between these two vital resources. Herein, hierarchical MXene nanosheets and bismuth vanadate (TiC/BiVO)-derived microcapsules were synthesized for a photothermal-induced photoredox reaction for twofold applications, namely, solar-driven water evaporation and hydrogen (H) production.

A-site deficient semiconductor electrolyte Sr Co FeO for low-temperature (450-550 °C) solid oxide fuel cells.

Fast ionic conduction at low operating temperatures is a key factor for the high electrochemical performance of solid oxide fuel cells (SOFCs). Here an A-site deficient semiconductor electrolyte Sr Co FeO is proposed for low-temperature solid oxide fuel cells (LT-SOFCs). A fuel cell with a structure of Ni/NCAL-SrCoFeO -NCAL/Ni reached a promising performance of 771 mW cm at 550 °C.

Tunable magneto-optical and interfacial defects of Nd and Cr-doped bismuth ferrite nanoparticles for microwave absorber applications.

Tunable microwave absorption characteristics are highly desirable for industrial applications such as antenna, absorber, and biomedical diagnostics. Here, we report BiNdCrFeO (x = 0, 0.05, 0.

Application of a Triple-Conducting Heterostructure Electrolyte of BaSrCoFeZrYO and CaCeSmO in a High-Performance Low-Temperature Solid Oxide Fuel Cell.

Dual-ion electrolytes with oxygen ion and proton-conducting properties are among the innovative solid oxide electrolytes, which exhibit a low Ohmic resistance at temperatures below 550 °C. BaCoFeZrYO with a perovskite-phase cathode has demonstrated efficient triple-charge conduction (H/O/e) in a high-performance low-temperature solid oxide fuel cell (LT-SOFC). Here, we designed another type of triple-charge conducting perovskite oxide based on BaSrCoFeZrYO (BSCFZY), which formed a heterostructure with ionic conductor CaCeSmO (SCDC), showing both a high ionic conductivity of 0.
