Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

open access: yesEcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Directed Hole Localization Stabilizing Interfacial Sulfur Species to Boost α‐C–H Activation for Selective Biomass Photo‐oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Efficient α‐C–H bond activation and directional conversion for selective biomass photo‐oxidation are achieved by integrating polarization and interface engineering strategies in P‐doped ZnIn2S4 polar photocatalysts, which leverage hole localization and stable interfacial sulfur species, endowing bio‐based HMF at 94.4% conversion with 94.5% selectivity ...

Optimally Carbonized Mangrove Wood–Derived Hard Carbon with a Soft Carbon Coating for High‐Performance Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).
