摘要：

P3HT-g-C3N4 photocatalysts with high activity have been fabricated by assembling p-type P3HT particles on n-type g-C3N4 nanoplates via a ball milling method. The photocatalytic activity of the P3HT-g-C3N4 photocatalysts for the degradation of MB was 2 times higher than that of pure g-C3N4. The formation of a heterojunction interface of P3HT-g-C3N4 photocatalysts enhanced the separation efficiency of photogenerated electron-hole pairs and resulted in the enhancement of photocatalytic performance. The potential difference in the heterojunction is the main driving force for efficient charge separation and transfer.
