Summary: Constructing photocatalysts with excellent visible light utilization efficiency and high-efficiency photo-generated charge transfer rate is crucial for the photodegradation of organic pollutants in wastewater. In this study, oxygen-doped graphitic carbon nitride (g-C3N4) was prepared and used as a responsive material for a wide range of visible light. CdS nanoparticles were then anchored onto the g-C3N4 to form a Z-scheme heterojunction, which facilitated interfacial charge separation. The results showed that the oxygen-doped g-C3N4/CdS-3 displayed a significantly higher degradation rate for 2-chlorophenol compared to g-C3N4.

However, pristine ferroelectric or pizeoelectric semiconductors are limited by insufficient polarization and spectral absorption. In this study, Bi4Ti3-2nCrnNbnO12/x-g-C3N4 (BTCNO-n/x-CN) heterojunctions were prepared by loading ultrathin g-C3N4 on ferroelectric BTCNO synthesized with co-doping of Cr3+-Nb5+ pairs. The doping not only enhances the piezoelectric performance of the heterojunctions but also promotes spectral absorption, leading to improved photocatalytic performance.
