| Summary: | The purpose of this paper is to describe and evaluate hydrogen gas production through the
corrosion of low carbon steel using electrochemistry. Electrolytes of varying pH (1 to 14) were
used in this research to find the pH that produced the lowest overpotential and thus lowest
consumption of electrical energy. Other electrochemical techniques, namely CV and EIS, were
used to find the Cdl and thus ECSA. The experiments were conducted using a 3-electrode system.
Scanning electron microscopy (SEM) was employed to observe the morphology before and after
the corrosion of the surface of low carbon steel. SEM EDS and X-ray Diffraction (XRD) was
also employed to detect the different elements present. In addition, the effect of surface
roughness on HER was also investigated in this study. |
