Technology Trends in Stainless Steel for Water Splitting Application

초록

Stainless steel, which includes Ni and Cr with Fe balance, is most often applied for a wide range of applications such as structure and equipment material. It is not only suitable for use in these applications due to its good corrosion resistance, but also can be applied to catalyst, supporting material, and current collector due to intrinsic properties of Ni and Fe contained in stainless steel. Therefore, in recent years, a lots of surface treatment methods have been studied to activate stainless steel, developing application of water splitting system. In this review paper, the research on the surface treatment technology of stainless steel for water splitting is summarized. It is expected to be able to propose the diverse surface treatment approaches of stainless steel for application to low-cost and highly efficient water splitting electrode.
