Modulating Electronic Structure of Atomic Iron Catalyst by Metallic Cobalt Cooperation for Boosting Oxygen Reduction/Evolution Reactions in Rechargeable and Flexible Zinc‐Air Battery

open access: yesCarbon Energy, EarlyView.
Porous Co,Fe@NCNF‐900 catalyst has been innovatively synthesized as enhanced bifunctional catalysts by modulating the electronic structure of the atomic Fe catalyst through metallic Co cooperation. DFT analysis indicates that metallic Co as an electron donor can induce electron redistribution of the atomic Fe catalyst, thereby reducing the rate ...

Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

open access: yesCarbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

Synergetic Heterophase and Selective Defect Engineering of Nano Multicomponent Alloys for Rechargeable Zn–Air Batteries

open access: yesCarbon Energy, EarlyView.
An fcc/bcc with defects (bcc‐d) MCA is designed by utilizing the interplay between heterophase and selective defect engineering and exhibits excellent electrocatalytic activity suitable for high‐performance zinc–air batteries. The synergistic catalysis of the fcc/bcc‐d breaks the universal linear‐scaling relationships of adsorbed multi‐intermediates ...
