In addition, when the pure water was selected as electrolyte instead of KOH solution, the TENG-driven system produces four H 2 bubbles in 90 s with a voltage of 10 V that is four times the electrochemical workstation. This indicates that the high voltage of the TENG is capable of prevailing over the high load, which is also the advantage of TENG in pure water electrolysis.
