| Abstract Scope |
The iron and steel making industry is indispensable for today’s society but is the largest industrial emitter of carbon dioxide. The use of hydrogen and renewable electricity for iron ore reduction could eliminate the need for carbon-based energy carriers and reducing agents. In recent years, a growing body of research shows the ability of non-thermal hydrogen plasmas to reduce iron ore. Nonetheless, the underlying mechanisms remain not well understood. In this presentation, we will report on a set of detailed measurements of iron ore reduction under highly controlled environments which enable us to shed light on the underpinning mechanisms and rate limiting steps. This includes in situ reduction measurements of iron nanoparticles which shed light on the chemical reactions and rates and the ex situ analysis of thin film iron oxide reduction which allows us to shed light on the growth of the iron phase in an iron oxide film. |
