THE INFLUENCE OF POLYACRYLAMIDE (PAA) ON HYDROGEN EVOLUTION REACTION AT THE POLYCRYSTALLINE GOLD

THE INFLUENCE OF POLYACRYLAMIDE (PAA) ON HYDROGEN EVOLUTION REACTION AT THE POLYCRYSTALLINE GOLD

The influence of polyacrylamide (PAA; Mn between 5∙103 and 1.5∙106 gmol-1 ) on hydrogen evolution reaction at the polycrystalline gold in 0.5 M H2SO4 was studied using potentiodynamic measurements (5 mV/s) in the potential range from 0 to -0.6 V/she. It was concluded that formation of protective lay...
