Research Abstract

Hydrogen evolution reaction at Cu and Ag electrodes is significantly accelerated by the addition of some organic molecules into the electrolyte solution. The mechanism of the acceleration has been investigated at molecular level by using surface-enhanced infrared absorption spectroscopy. We also tried to enhance the catalytic activity of photocatalysts toward hydrogen evolution reaction by combining such molecular catalysts. Although the trial has not been succeeded yet, infrared analyses of photocatalysts provided new information about the dynamics of photo-generated charge carriers.
