Photo-electrochemical characterization of polypyrrol: Application to visible light induced hydrogen production

The semi-conducting properties of polypyrrol (PPy) are investigated by the photo-electrochemical technique. The polymer is stable up to~190°C, above which a weight loss accounting for~60% is observed. An optical transition of 1.02eV is determined, directly allowed. Further indirect transition is det...
