An efficient g-C3N4-based organic hybrid photocatalyst with PEDOT:PSS as a hole-transporting material

Abstract

An efficient g-C3N4-based organic photocatalyst was synthesized by hybriding with a hole-transporting material, poly(3,4-ethylenedioxythiophene) poly(styrene sulfonate) (PEDOT:PSS). The PEDOT:PSS/g-C3N4 hybrid showed much enhanced photocatalytic activity for Rhodamine B degradation under simulated sunlight irradiation. When the hybridization amount of PEDOT:PSS was 0.25 wt%, the sample exhibited maximum photocatalytic activity, which was about 3 times as high as that of pure g-C3N4. Based on the photoelectrochemical and photoluminescence measurements, the possible charge transfer mechanism of enhanced photocatalytic activity was proposed.
