Some features of hydrogen evolution reaction on iron with surfactant on the example of o-fluorophenylbiguanidine

It has been shown that, when there is o -fluorophenylbiguanidine ( o -FPBG) and its concentration increases (from 0.5 to 40 mM), the change of the nature of slow step of hydrogen evolution on iron is observed in the following order: slow discharge → limiting chemical recombination → slow lateral dif...

Description
Summary:It has been shown that, when there is o -fluorophenylbiguanidine ( o -FPBG) and its concentration increases (from 0.5 to 40 mM), the change of the nature of slow step of hydrogen evolution on iron is observed in the following order: slow discharge → limiting chemical recombination → slow lateral diffusion → limiting discharge. This series is in sufficient correlation with the experimental adsorption isotherm of o -FPBG on iron.
