Mechanistically Interpretable Artificial Intelligence for Designing Oxygen Electrocatalysts

Advanced Materials, EarlyView.
Mechanistically interpretable artificial intelligence screens nearly seven million perovskite compositions and identifies key descriptors—d‐p hybridization and densification resistance—that govern oxygen electrocatalysis. The discovered BaCo0.8Nb0.1Zr0.1O3‐δ achieves a record 2.68 W cm−2 peak power density at 600°C with over 500 h of durable operation ...

Selective Electrochemical NOx Reduction to N2 for Sustainable Ammonia Energy Systems

Advanced Materials, EarlyView.
Selective electrochemical NOx reduction to N2 offers a promising route to mitigate combustion‐derived NOx emissions in ammonia energy systems. This Perspective links *NO‐mediated pathways, the key intermediate role of N2O, and low‐coverage limitations to the origins of limited N2 selectivity, establishing tandem catalysis and microenvironment ...
