Manipulating the Spin State of Perovskite Cs3Bi2Br9 by Co‐Doped for Efficient Photocatalytic CO2 Reduction

open access: yesAdvanced Science, EarlyView.
The photocatalytic conversion of CO2 into the renewable fuels is a promising strategy to address energy and environmental challenges. Here, we reported a spin‐polarization strategy using Co2+ doping in lead‐free perovskite Cs3Bi2Br9 synergized, to achieve highly efficient CO2 reduction.

Defect‐Engineered CoSe2 Quantum Dots Exposing Highly Active (111) Facets with Lithiophilic‐Sulfurophilic Functionality for High‐Energy Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Defective CoSe2 QDs confined within carbon microspheres (CoSe2@C) are prepared as an advanced sulfur cathode host material. The exposure of highly active (111) facets and the abundant selenium vacancies not only provides more active sites but also accelerates the catalytic conversion dynamics and lowers the reaction energy barrier of Li–S batteries ...

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 ...
