Fund Project: This work was supported by the National Natural Science Foundation of China (21573085 and 51872108), the Wuhan Planning Project of Science and Technology (2018010401011294), and the self-determined research funds of Central China Normal University (CCNU) from the college's basic research and operation through the Chinese Ministry of Education (CCNU18TS034).

TiO₂ nanoparticles were prepared using the hydrothermal method and modified with C₃N₄ to synthesize a Type-II heterojunction semiconductor photocatalyst, TiO₂-C₃N₄. In addition, a carbon layer was coated onto the TiO₂ nanoparticles and the obtained material was uniformly covered on the surface of C₃N₄ to form an all-solid-state Z-scheme semiconductor photocatalyst, TiO₂-C-C₃N₄. Through characterization by XRD, XPS, SEM, TEM, BET, photoelectrochemical experiments, UV-visible diffuse reflection, and PL spectroscopy, the charge transfer mechanism and band gap positions for the composite photocatalysts were analyzed. The Type-II and all-solid-state Z-scheme heterojunction structures were compared. By combining microscopic internal mechanisms with macroscopic experimental phenomena, the relationship between performance and structure was verified. Experimental methods were used to explore the adaptation degree of different photocatalytic mechanisms using the same degradation system. This study highlights effective photocatalyst design to meet the requirements for specific degradation conditions.
