Tracking high-valent surface iron species in the oxygen evolution reaction on cobalt iron (oxy)hydroxides

A comparative study of the oxygen evolution reaction on oxidised nickel, cobalt and iron electrodes in base

Despite the recent renewal in interest in the oxygen evolution reaction (OER) at transition metal oxide based electrodes in alkaline solution, the details of the mechanism remain controversial. While most studies focus on a particular oxide in isolation, a consistent experimental examination of the oxides of adjacent elements is likely to be fruitful with respect to mechanistic elucidation. In ...

H2O2 oxidations catalyzed by an iron(III) corrolazine: avoiding high-valent iron-oxido species?

Response surface method Optimization of the Dyes Degradation using Zero-Valent Iron based Bimetallic Nanoparticle on the Bentonite Clay Surface

Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...
