Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

EcoEnergy, EarlyView.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

Rational Design and Operando Characterization of Hierarchical α‐FeOOH‐FeP/Ni3S2 Catalysts for High‐Rate Alkaline Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A hierarchical FeOOH–FeP@Ni3S2 electrocatalyst is engineered on 3D Ni foam to enable efficient alkaline oxygen evolution. Operando spectroscopic techniques reveal dynamic surface reconstruction and proton‐coupled electron transfer (PCET) kinetics. The catalyst exhibits low overpotential and industrial‐level current operation, driving high‐performance ...
