Tuning the Growth Pattern of Triangular Silver Nanoplates from Lateral to Vertical by Secondary Metal Addition

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
What happens, if in the synthesis of flat silver platelets, the slow deposition of silver along twinning faults is disturbed by the addition of a nobler metal? We have looked into it and found a way to fine‐tune the metal deposition in lateral and vertical direction.

Bimetallic Synergy in Cocatalyst Alloy Nanoparticles for Efficient Photocatalytic Hydrogen Production

EcoEnergy, EarlyView.
A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of

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.
