Serrated Leaf‐Like N‐Doped Copper Sulfide Enabling Bifunctional Oxygen Reduction/Evolution via Dual‐Mode Cathode Reactions for High Energy Density and Cycle Stability in Zinc–Air Batteries

open access: yesAdvanced Science, EarlyView.
A serrated leaf‐like nitrogen‐doped copper sulfide (N‐CuS) cathode with hybridized N 2p – S 3p orbitals is presented, mesopores for oxygen transport, and a five times larger electrochemical active surface area than Cu. In aerobic conditions, a zinc–air battery with N‐CuS achieves 788 mAh g⁻¹ and 916 Wh kg⁻¹, outperforming Pt/C+RuO₂.

Tunable High‐Performance Photo‐Assisted Li–O2 Batteries by the Construction of Ferroelectric Photocathode

open access: yesAdvanced Science, EarlyView.
xxx. Abstract Photo‐assistance is considered to be an effective approach to reducing the overpotential for lithium‐oxygen (Li–O2) batteries. However, the advancement is greatly hindered by the rapidly recombined photoexcited electrons and holes upon the discharging and charging processes.

Thermally Reconstructed Ru/La‐Co3O4 Nanosheets with Super Thermal Stability for Catalytic Combustion of Light Hydrocarbons: Induced Surface LaRuO3 Active Phase

open access: yesAdvanced Science, EarlyView.
The high‐temperature induced the exsolution of La from La‐Co3O4 lattice and facilitated the in situ formation of highly active LaRuO3 perovskite through a solid‐phase reaction with surface RuOx. This process significantly enhanced the thermal and hydrothermal stability of Ru/La‐Co3O4 for light hydrocarbons (LHs) oxidation, providing an innovative ...
