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

open access: yesEcoEnergy, 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 ...

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3−$$ {\mathrm{NO}}_3^{-} $$ coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous ...
