Synthesis of Carbon Nanotubes From CO2 Enabled by Fe–Mo Bimetallic Catalysts via Effective CO2 Scavenging

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.

Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

Synthesis of Single‐Crystalline Ni‐Rich Cathodes for Lithium‐Ion Batteries With Superior High‐Voltage Stability by Mo/Nb Dual Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel synthesis method of single‐crystalline LiNi0.8Co0.15Al0.05O2 (NCA) is introduced, involving the stripping of grain boundaries from polycrystalline NCA (PC‐NCA) during Mo/Nb co‐doping. Mo doping near the grain surface significantly reduces parasitic interface reactions and inhibits the excessive growth of CEI films, while Nb doping within the ...
