About Paper:

High Surface Area Iron-Nikel Electrodes For Electrochemical Applications. Co-Author(s): Manasa Rajeev, Andrew Goldman The Kempler Lab at the University of Oregon has developed a novel electrochemical method for producing iron. This advancement addresses the environmental challenges of traditional iron production while supporting the demand for affordable, high-performance materials in electrochemical systems. The aim of this study is to investigate whether high surface area iron produced through this method can serve as an effective alternative to conventional rare metal electrodes in energy-related applications. Through controlled electrochemical synthesis, the lab identified optimal forms of iron oxide and process conditions that yield iron sheets with exceptionally high surface areas. These materials were tested for their potential use as electrodes. Early results show that iron and iron-nickel composites produced through this method exhibit promising characteristics, including enhanced conductivity, surface reactivity, and economic feasibility. This is especially important in replacing electrodes made from rare and costly metals such as platinum and gold. The findings suggest that iron-based electrodes offer a sustainable and accessible solution for the development of low-cost, efficient electrodes critical to advancing renewable energy and industrial electrochemical processes. 150 UNIVERSITY OF OREGON • 2025 UNDERGRADUATE RESEARCH SYMPOSIUM TABLE OF CONTENTS
