Abstract

The rate equation of hydrogen evolution reaction on spheroidal graphite cast iron which has different areas of graphite particles has been studied in sulfuric acid solutions at 298 K. The cathodic Tafel slope of −0.125 V/decade and the reaction order with respect to the activity of hydrogen ion of 1 are obtained by linear potential sweep technique. The cathodic current density due to hydrogen evolution reaction does not depend on the area of graphite particles. There is no difference in hydrogen evolution reaction mechanism between pure iron and spheroidal graphite cast iron.
