The oxygen evolution reaction (OER) is the bottleneck of electrochemical water-splitting process, where use porous metal oxide electrodes beneficial. In this work, we introduce a one-pot synthesis method to fabricate series mesoporous cobaltite (m-MCo2O4, M = Mn, Ni, and Zn) for OER. involves preparation coating homogeneous clear solution all ingredients (metal salts surfactants) over fluorine-...
An effective integrated design with a free standing and carbon-free architecture of spinel MnCo2O4 oxide prepared using facile and cost effective hydrothermal method as the oxygen electrode for the Li-O2 battery, is introduced to avoid the parasitic reactions of carbon and binder with discharge products and reaction intermediates, respectively. The highly porous structure of the electrode allow...
In order to increase the efficiency and working life of mettalic interconnects used in solid oxide fuel cells, protective coatings with high electrical conductivity are used. In this study, AISI 430 ferritic stainless steel was coated in a cobalt-base pack mixture by pack cementation. The effect of oxide thickness on the area specific resistance (ASR) was investigated by applying isothermal ox...
The application of conductive coatings on ferritic stainless steel can decrease electrical conductivity. Theaim of this research was to investigate the electrical conductivity of cobalt coated AISI 430 ferritic stainlesssteel by pack cementation technique. Coated coupons were analyzed using scanning electron microscopy(SEM). Electrical conductivity of the coated substrates was measured as a fun...
