| Summary: | The properties of stainless steel are possible to be used as electrode in the
other hand its catalytic activity needs to be increased. Hence it�s necessary to be
coated with metals which have catalytic properties, i.e. Fe, Co and Ni on stainless
steel substrate. Fe, Co and Ni metals do not only have catalytic activity but also have
the same size, identical properties, abundance and inexpensive.
The preparation and characterization of stainless steel/Fe-Co-Ni has been
studied for electrocatalyst of hydrogen evolution reaction. The purpose of the
research is improving the properties of stainless steel as electrode of water
electrolysis to have catalyst activity for hydrogen evolution reaction. The stainless
steel/Fe-Co-Ni electrodes were prepared by coating the stainless steel substrate with
singular Fe, Co, and Ni metals, binary Fe-Co, Fe-Ni, and Co-Ni composites, and
ternary Fe-Co-Ni composites, using linear voltammetric method with stainless steel
as working electrode, Ag/AgCl as reference electrode and platinum as counter
electrode. The ternary electrodes were prepared under the variation of Fe content
(stainless steel/Fe1-5-Co-Ni). The stainless steel characters were determined by
scanning electron microscopic-energy-dispersive X-ray spectroscopy (SEM-EDX),
optical emmision spectrometer (OES), voltammetric and gas sorption analyzer
(GSA). The characters of the singular and binary electrodes were determined by SEM
and voltammetric methods
