Molecular Engineering of g-C3N4 with Dibenzothiophene Groups as Electron Donor for Enhanced Photocatalytic H2-Production
文献摘要：
The construction of donor-acceptor (D-A) molecular structure is an attractive strategy to enhance the photocatalytic performance of polymeric semiconductors. Herein, dibenzothiophene (DBT)-4-carbaldehyde as the precursor is introduced into g-C3N4 (TCN) prepared by two-step thermal polymerization to construct an intramolecular D-A type copolymer (TCN-DBTx). DFT calculation and experimental results reveal that DBT plays the role of electron donor unit to modify g-C3N4. The incorporation of DBT not only adjusts the band gap to im-prove reduction ability, but also induces an internal electric field with extending π-conjugated system for effective charge transfer. As a result, TCN-DBTx exhibits much better photocatalytic performance with an optimal hydrogen production rate of 3334 μmol h-1 g-1, which is 2.5 times that of TCN. This work provides a protocol for preparing high-performance g-C3N4-based photocatalysts toward various applications.
