Beyond Density: Unveiling the Trade‐Off in Catalytic Site Optimization Using Defect‐Engineered UiO‐66

open access: yesAdvanced Science, EarlyView.
A well‐designed experimental model reveals a trade‐off between intrinsic activity and catalytic site density in performance optimization, due to inherent diffusion resistance arising from substrate adsorption at catalytic sites. Abstract Enhancing intrinsic activity and increasing catalytic site density are two widely employed strategies to improve ...

Upcycling Spent Graphite Anodes into Bifunctional Photothermal Catalysts for Efficient PET Chemical Recycling

open access: yesAdvanced Science, EarlyView.
Waste graphite anodes from spent lithium‐ion batteries serve as a sustainable lithium source for synthesizing lithium ethylene glycolate. This reactive species efficiently catalyzes PET depolymerization under mild conditions, achieving rapid and selective monomer recovery.

Strong Internal Electric Field‐Driven S‐scheme CoAl‐LDH/ZrO2 Heterojunction for Enhanced Photocatalytic CO2 Reduction: Configuration, Performance, and Mechanism

open access: yesAdvanced Science, EarlyView.
This study constructed an S‐scheme heterojunction catalyst CoAl‐LDH/ZrO2 driven by an internal electric field. The S‐scheme heterojunction accelerated charge separation and strengthened redox capability synergistically contribute to the superior CO2 reduction performance.Under simulated solar irradiation, optimal catalyst exhibited a CO production rate

Carboxyl‐Guided Ultrafine Zinc‐Acetate Templating Enables Closed‐Pore Engineering in Coal‐Derived Hard Carbon Anodes for High‐Performance Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
In this study, ≈2 nm zinc acetate templates are uniformly anchored on the surface of NaOH‐etched bituminous coal via chelation between carboxyl groups and Zn2+. Subsequently, phenolic resin encapsulation is employed to construct a hard carbon material with abundant closed‐pore structures, achieving a reversible capacity of 370.9 mAh g−1 and an ICE of ...
