Efficient non-metal based conducting polymers for photocatalytic hydrogen production: comparative study between polyaniline, polypyrrole and PEDOT.

ABSTRACT: Incorporation of conducting polymers (CPs) with TiO₂ is considered a promising pathway toward the fabrication of highly efficient non-metal based photocatalysts. Herein, we report the fabrication of TiO₂@polyaniline, TiO₂@polypyrrole, and TiO₂@poly(3,4-ethylenedioxythiophene) photocatalyst heterostructures via the facile wet incipient impregnation method. The mass ratios of CPs in the composites were optimized. The structure, morphology, optical and surface texture of the samples were characterized by XRD, TEM, TGA, DRS, and N₂-physisorption techniques. The TiO₂@2PEDOT, TiO₂@2PPy, and TiO₂@5PAn composites were found to exhibit the highest H₂ evolution rate (HER) of 1.37, 2.09, and 3.1
