Abstract

Electrochemical properties and electrocatalytic activity in of hydrogen evolution reaction (HER) in new members of the family of homogeneous organic metal-free catalysts based on N-methyl and N-phenyl - 2,4,6-triphenylpyridinium perchlorates were studied using electrochemical methods. With a similar structure and electrochemical properties, the electrocatalytic behavior differs dramatically. The main reason for this is the
