Consecutive electrochemical processes in controlled potential electrolysis

Abstract

The fundamental relations pertaining to the controlled potential electrolysis of a reaction path which involves two consecutive irreversible electrochemical reactions have been derived. The results show that in the true mass transport limiting current region, the conditions are such that no intermediates appear and plots of log i vs. t should be linear. This result is contrary to previous findings. The conditions necessary for the isolation of intermediates are discussed.
