Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

Small, Volume 22, Issue 52, 16 September 2026.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

Compositional and Fabrication Cycle Optimization of Ceria-Zirconia-Supported Mo-Based Catalysts for NH₃-SCR NO_x Reduction

Inorganics
The reduction of nitrogen oxides (NOx), critical pollutants from stationary to mobile sources, mainly relies on the selective catalytic reduction (NH3-SCR) method, employing ammonia to reduce NOx into nitrogen and water.

Subnanometer Copper Clusters of Five Atoms on Titania Boosting CO2 Conversion to Methane

Small Structures, Volume 7, Issue 9, September 2026.
Supported five‐atom copper clusters (Cu5/TiO2) demonstrate exceptional catalytic performance for CO2 methanation, achieving 100% methane selectivity at 300 °C. Operando X‐ray absorption near‐edge structure (XANES) and DFT calculations reveal a preferred methoxy‐mediated pathway and reversible redox behavior.
