Abstract

Herein we report on the synthesis of a ternary polymer composite of graphene, carbon nitride, and poly(3-hexylthiophene) (G-g-C3N4-P3HT) by a solvothermal method. The prepared polymer composite catalysts are characterized by TEM, XRD, FTIR spectroscopy, and photoluminescence techniques for their morphology, structure and photocatalytic efficiency. Graphene-loaded polymer composites of carbon nitride (g-C3N4) and poly(3-hexylthiophene) act as efficient photocatalysts for waste water treatment. Methylene blue is used as the model pollutant and the rate of its photocatalytic degradation with G-g-C3N4-P3HT is three times higher than that achieved with a g-C3N4-P3HT composite.
