Abstract A nickel ferrite was prepared by a liquid‐phase method and used as an oxygen evolution catalyst in anion exchange membrane electrolyser. complete physicochemical characterization of the performed through X‐ray diffraction (XRD), Transmission electron microscopy (TEM) photoelectron spectroscopy (XPS). Then, deposited spray coating technique onto Fumasep® FAA3‐50 anion‐exchange to realiz...

The present study deals with the pitting and repassivation behavior of a nickel-reduced austenitic stainless steel different nitrogen contents. While promoted resistance to pitting, no significant effect on was found. also aims address experimental difficulties in determining potentials owing occurrence crevice corrosion. Furthermore, mechanism ongoing reactions investigated, indicating that in...

We report here on an efficient one-step-impregnation method to synthesize crystalline mesoporous bimetal oxides (e.g. NiFe(2)O(4), CuFe(2)O(4), Cu/CeO(2)) using mesoporous silicas as hard templates under optimized mixing conditions. This new procedure enables a true replication of the mesostructure with high yield and phase purity, while retaining particle morphology of the template.
