Zr Incorporation Into Lithium Nickel Oxides: Bulk or Surface Substitution?

open access: yesAdvanced Science, EarlyView.
Mechanism of Zr incorporation into lithium nickel oxide (LNO) cathodes is studied from atomistic to macroscale. Zr doping enhances cyclability of Li‐ion batteries with LNO via bulk, interface, and grain boundary optimization leading to structural integrity at atomistic‐ and micro‐scale of secondary particle aggregates.

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

open access: yesAdvanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).
