my doubt is what is the use of Electrochemical workstation CHI in photocatalytic water splitting. how is it helpful in my research? what are other electrodes (reference etc) ? what are there physical significance?
Each instrument is designed to do some job. How the instrument is useful for your project depends on YOUR skills, but not on the instrument. You must know very well your field of research and capability of the instrument. Your question clearly indicates that you need to learn basics of electrochemistry. The RG forum is not designed for teaching.
