Improving in operando low field NMR copper electrodeposition analyses using inductively coupled coils
To unveil the reaction pathway in electrochemical systems, knowledge of the reaction intermediates and the concentrations of reagents and products would be very useful. Nuclear magnetic resonance (NMR) is the most popular technique for elucidating molecular structures and is well suited for in situ coupling with electrochemistry. In this work we explore how to improve the sensitivity of NMR for monitoring electrochemical processes in situ with the help of inductively coupled coils. We show that a secondary coil in the NMR probe is beneficial for monitoring the change in the H-1 T-2 values during the electrodeposition reaction of Cu2+, which are closely related to the concentration of Cu2+ in the solution.
