Chemical reduction of hexavalent chromium (VI) in soil slurry by nano zero valent iron [PDF]

, 2015
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil

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.

Dual‐Molten‐Salt Etching Strategy Enables Built‐in Electric Field in Mo‐MXene/NiFeSe Heterostructure for Superior OER Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐molten‐salt etching strategy was employed to construct a built‐in electric field in the Mo‐MXene/NiFeSe heterostructure to achieve excellent oxygen evolution reaction. Transition metal selenides have emerged as potential catalysts for the oxygen evolution reaction, yet their practical implementation faces two fundamental challenges: irreversible
