“…27 However, due to the weak crystalline nature of g-C 3 N 4 , the lattice fringes of g-C 3 N 4 were indistinct compared with ZnBi 2 O 4 , which is in better agreement with the XRD results. 34 Furthermore, the formation of the intimate interfacial bonds and grain boundaries between g-C 3 N 4 and ZnBi 2 O 4 is clearly seen in the HRTEM image. Due to the defect formation in the interfacial bonds, these sites could act as trapping centers and result in the enhanced photocatalytic activity via the reduction of photoinduced carrier recombination.…”

Photocatalytic technology has been widely studied, discussed, and tested as a feasible wastewater degradation technology. The present study demonstrated the preparation of g‐C3N4 material using solid‐state sintering method and the construction of Bi4Ti3O12/g‐C3N4 heterostructure via hydrothermal method. This direct contact Z‐type heterojunction improves the wide bandgap of Bi4Ti3O12 monomer, enhances its photoresponsiveness, and thus improves its photocatalytic performance. During the process of photocatalytic experiments, an environment of cold and hot fluctuations were created, and the pyroelectric effect was utilized to induce self‐polarization of the material and formed an internal electric field. It improves the transport ability of electron–hole pairs and suppresses their recombination in the transport path. According to the degradation experiment results, the degradation efficiency of pyroelectric synergistic heterojunction photocatalysis reached 88.7%, which was 2.27 times that of Bi4Ti3O12. It proves that the photocatalysis by pyroelectric synergistic heterojunction has good application prospects.

This study presents a novel ternary Ag3PO4/g‐C3N4/zeolite composite for photocatalytic H2 production and TC degradation through S‐scheme electron transport. The S‐scheme Ag3PO4/g‐C3N4 heterojunction was successfully constructed on zeolite surface through calcination and precipitation processes. The results indicated that Ag3PO4/g‐C3N4/zeolite‐50% presented dramatically enhanced photocatalytic TC degradation performance, and the TC degradation efficiency was up to 92.86% in 180 min under visible light. The corresponding reaction rate constant was 0.01205 min‐1 which was 2.18 and 7.48 times greater than those of pure Ag3PO4 (0.00554 min‐1) and g‐C3N4 (0.00161 min‐1), respectively. Meanwhile, the highest H2 production rate (2748.6 µmol•g‐1•h‐1) was achieved over Ag3PO4/g‐C3N4/zeolite‐50% under simulated solar light which was around 26.5 and 5.6 times higher than that of g‐C3N4 and Ag3PO4, respectively. The enhanced photocatalytic activity of the ternary composite was mainly due to the synergistic effect of S‐scheme Ag3PO4/g‐C3N4 heterojunction and zeolite support which endowed the composite with excellent adsorption activity, enhanced light response ability, and efficient separation of photoinduced carriers. TC degradation mechanism and pathways were proposed based on quenching experiment and HPLC‐MS results. Overall, this study proposes a promising strategy for significantly improving photocatalytic activity and applying in photocatalytic pollutant degradation and hydrogen production.
