Ruihan’s paper describes a unique catalyst that contains no precious or platinum-group metals, as is most common for water oxidation in acid. Instead, Ruihan tunes the activity and stability of earth-abundant manganese oxides by incorporating chlorine to result in a heteroanionic material that exhibits excellent activity and stability for acidic oxygen evolution. Her work takes a deep dive into the structural and activity evolution, using a combination of ex situ and in situ surface and bulk-sensitive X-ray spectroscopy analyses. This study provides insights into the fundamental relationships between the chemical, electronic, and geometric properties of the catalysts and their electrocatalytic outcomes. Congratulations Ruihan!
