Summary: Atom trapping leads to catalysts with atomically dispersed Ru1O5 sites on (100) facets of ceria, showing excellent activity in catalytic NO oxidation and high NOx storage properties. The Ru1O5 sites exhibit higher stability during calcination and the Ru1/CeO2 catalyst is stable during continuous cycling and in the presence of moisture. In addition, the catalyst shows excellent reactivity for NO reduction by CO at low temperatures. This study highlights the applicability of novel ceria-based single-atom catalysts in NO and CO abatement.

Summary: The direct electrochemical nitric oxide reduction reaction (NORR) is an attractive technique for converting NO into NH3 with low power consumption under ambient conditions. Optimizing the electronic structure of the active sites can greatly improve the performance of electrocatalysts. In this study, body-centered cubic RuGa intermetallic compounds (bcc RuGa IMCs) were prepared via a substrate-anchored thermal annealing method. The electrocatalyst showed a remarkable NH4+ yield rate of 320.6 mu mol h(-1) mg(Ru)(-1) with a corresponding Faradaic efficiency of 72.3% at a very low potential of -0.2 V vs. reversible hydrogen electrode (RHE) in neutral media. Theoretical calculations revealed that the electron-rich Ru atoms in bcc RuGa IMCs facilitated the adsorption and activation of *HNO intermediate, thus greatly reducing the energy barrier of the potential-determining step in NORR.

Summary: Researchers developed a structurally ordered PtRhFeNiCu high-entropy intermetallics as an electrocatalyst for high-temperature polybenzimidazole-based direct ethanol fuel cells, exhibiting excellent electrocatalytic activity and CO tolerance. The power density achieved was 47.50 mW/cm(2), 2.97 times higher than Pt/C. The new class of high-entropy intermetallics showed better C-C bond-breaking ability, stability, and electrochemical activity compared to high-entropy alloys and Pt/C catalysts.
