Preparation of porous Ni-Co sinters by subsequent oxidation/reduction method

摘要

The study of oxidation/reduction processes of Ni-Co powders containing a different content of cobalt was presented. The processes of oxidation in air atmosphere as well as reduction in hydrogen atmosphere were examined by thermogravimetric measurements. The characteristics of chemical and phase composition were determined by EDS and XRD methods. The morphology of the sinters was analyzed with SEM method. The research was done for the potential application of Ni-Co sinters as precursors of electrodes for hydrogen evolution from an alkaline environment.
