Atomically Dispersed Zr‐N Moieties Modulate Fe Coordination for Robust Oxygen Reduction Electrocatalysis

Advanced Science, EarlyView.
The introduction of atomically dispersed Zr‐N moieties adjacent to Fe‐N4 centers forms a bimetallic coordination configuration. This structure modifies the local electronic environment of the Fe sites, weakening the adsorption of OH intermediates, suppressing Fe agglomeration and dissolution, and consequently enhancing both the catalytic activity and ...

Cu3SbSe3‐Alloying‐Induced High Thermoelectric Performance and Mechanical Robustness in Bi2Te3‐Based Thermoelectric Materials

Advanced Science, EarlyView.
Combining microstructural engineering with Cu3SbSe3 alloying significantly improves the performance of Bi2Te3‑based thermoelectric materials, yielding a high zT of ≈1.45 (average zT ≈1.3 over 303–503 K), excellent mechanical robustness (Vickers hardness of 96 Hv and compressive strength of 187 MPa), and an impressive conversion efficiency of ≈6.9% at a

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

Advanced 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 ...

Grow p‐type MoS2 on FeNC for CO2 Sensing in Complex Environments with Intelligent Recognition

Advanced Science, EarlyView.
In situ growth of p‐type MoS2 (p‐MoS2) on N‐ and Fe‐enriched carbon (FeNC) nanosheets allows for detection of carbon dioxide (CO2) fluctuation levels as low as 50 ppm at 25 °C. The induced S vacancies (Svacs) and the modulated electron distribution jointly improved sensing selectivity to CO2. Abstract A wealth of theoretical studies demonstrates p‐type
