DOI: 10.1002/aenm.202404689
Abstract: Fe‐based single‐atomic catalysts (SACs) are considered the most promising non‐precious oxygen reduction reaction (ORR) catalysts, whereas further development is largely hindered due to the unavoidable Fenton reaction during the ORR process. Herein rare‐metal Ce‐based SACs… read more here.

Abstract: The bifunctional oxygen electrocatalyst is the Achilles' heel of achieving robust reversible Zn-air batteries (ZABs). Herein, durable bifunctional oxygen electrocatalysis in alkaline media is realized on atomic Fe-N4-C sites reinforced by NixCo3-xO4 (NixCo3-xO4@Fe1/NC). Compared with… read more here.

DOI: 10.1021/jacs.3c09533
Abstract: Potassium-sulfur (K-S) batteries are severely limited by the sluggish kinetics of the solid-phase conversion of K2S3/K2S2 to K2S, the rate-determining and performance-governing step, which urgently requires a cathode with facilitated sulfur accommodation and improved catalytic… read more here.
