A dual polymer composite of poly(3-hexylthiophene) and poly(3,4-ethylenedioxythiophene) hybrid surface heterojunction with g-C₃N₄ for enhanced photocatalytic hydrogen evolution.

ABSTRACT: A surface heterojunction catalyst of g-C₃N₄-PEDOT/P3HT with P3HT and PEDOT as the polymer sensitizer and hole transport pathway is successfully prepared. The as constructed g-C₃N₄-PEDOT/P3HT composite exhibits a photocatalyst H₂ evolution rate up to 427703.3 μmol h^-1 g^-1 which is 1059 times higher than that of g-C₃N₄, 118 times higher than that of g-C₃N₄-PEDOT with ascorbic acid as sacrificial reagents. What's more, the g-C₃N₄-PEDOT/P3HT can even show an obviously enhanced photocatalytic H₂ evolution rate which is 6.1 times higher than that of pure g-C₃N₄ in pure water without any sacrificial reagent.
