The research data is subdivided into experimental (Chapters 2-4) and modelling data (Chapter 5). Experimental data contains: raw and processed data from electrochemical measurements, product calibration for quantification and material characterization techniques. In order to access most of the data used for the figures, including the figures itself, graphical design software Origin Pro is required. The electrochemical data reported in Chapter 2 and 4 can be opened by EC-Lab software. However, the Origin Pro files used for the graphical figures also contain processed raw data. The models used for Chapter 5 were prepared in spreadsheet software, which are therefore easily accessible. Energy calculations and the design of separation process units were performed within the Aspen Plus simulation environment, and require a commercial license to access the simulation files.
