Doctorate for Fengli Yang
Fengli Yang defended her doctoral thesis at Freie Universität Berlin. She carried out research on the broader impact of impurity ions on the structure of Ni/Co-based electrocatalysts under electrochemical oxygen evolution reaction conditions.

One main objective of Fengli Yang’s PhD work was to track the incorporation of dilute iron (Fe) impurities into a transition metal oxide catalyst, since Fe is one of the most important impurities in electrocatalysts for the oxygen evolution reaction (OER) due to its significant influence in enhancing the activity when available in the optimum concentration.
Ms. Fengli Yang did her research within the Interface Science Department headed by Prof. Beatriz Roldan Cuenya in the Liquid Phase Electron and X-ray Microscopy Group lead by Dr. See Wee Chee.
During her defense, Ms. Yang presented an excellent knowledge on the scientific field. She has made outstanding contributions to our fundamental understanding of impurity effects in OER electrocatalyst, which might have a real impact in the field. “Today we had a wonderful thesis defense for Fengli and she was awarded Summa Cum Laude. I would like to congratulate her for this outstanding achievement,” says his PhD supervisor, Prof. Dr. Beatriz Roldan Cuenya.
The complete title of Fengli Yang’s dissertation is “Operando Insights into the Impact of Electrolyte Impurity Ions on the Structure of Ni/Co-based Electrocatalysts under Electrochemical Oxygen Evolution Reaction Conditions”.
