Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

A Novel Heterometallic Ring {Cr5Ni3} and New {Cr6Co2} and {Cr6Zn2} Rings

open access: yesChemistry – A European Journal, EarlyView.
A novel heterometallic ring containing five Cr(III) and three Ni(II) centers is reported. It forms an octagon and has a single isomer, as revealed by a combination of magnetic and EPR studies and collision‐induced dissociation mass spectrometry. ABSTRACT A new heterometallic ring, [Me4N][(Me4N)2Cr5Ni3F8(BTFB)16] (BTFB = 3,5‐bis(trifluoromethyl)benzoate)

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

open access: yesENERGY &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.
