Functionalization‐Mediated Synthesis of Bridge‐Coordinated Fe Atoms on MoS2 Nanosheets for PEM Water Electrolyzers

Angewandte Chemie, EarlyView.
We report a functionalization‐mediated strategy to synthesize robust iron (Fe) atoms selectively coordinated at bridge sites on molybdenum disulfide (MoS2) nanosheets. The resulting b‐Fe‐MoS2 catalyst exhibits enhanced activity and durability for the hydrogen evolution reaction in proton exchange membrane water electrolyzers compared to atop ...

Decouple H2O2 Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering

Angewandte Chemie, EarlyView.
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure

Advanced Energy Materials, EarlyView.
Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC
