Title
Photocatalytic Water-Splitting Using Organic Pigments As Semiconductors
Abstract
Twelve pigments are identified as possible water splitting photocatalysts using theoretical calculations. The HOMO and LUMO calculations are validated using ultraviolet photoelectron spectroscopy (UPS) to obtain gas phase ionization potentials (IP) and by cyclic voltammetry to obtain redox potentials. The pigments are tested in water splitting experiments and found to evolve both oxygen and hydrogen, when tested separately. The hydrogen levels are low which validate the predictions based upon the redox potentials. Several pigments are promising in terms of oxygen evolution and several are found to bleach extended irradiation. The use of polymer-bound organic pigments as semiconductors for dual-bed system is studied.
