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.

Summary: A bimetallic electrocatalyst based on copper and iron has been developed to efficiently convert all NOx-based species to NH3. The tunability of the d-band energy through introduction of iron to copper improves the adsorption energies of reaction intermediates. In situ Fourier transform infrared spectroscopy and density functional theory provide details of the reaction pathway. Electrochemical production of green NH3 from nitrogen oxide pollutants using renewable electricity is a sustainable solution for a serious environmental problem.

Summary: This study elucidates the selectivity and activity of metal catalysts for NOx electroreduction, with copper showing selective NH3 formation by binding *NO but not *H. Metals that do not bind NO stop the reaction at NO, similar to CO2-to-CO conversion. At higher potentials, a low barrier for N coupling with NO may lead to N2O formation.
