Hexagonal boron nitride (h‐BN) is one of the most attractive 2D materials because of its remarkable properties. Combining h‐BN with other components (e.g., graphene, carbonitride, semiconductors) to form heterostructures opens new perspectives to developing advanced functional devices. In this review, the state‐of‐the‐art in h‐BN heterojunctions is highlighted. The preparation of high‐quality 2D h‐BN structures with fewer defects can maximize its intrinsic properties, such as thermal conductivity and electrical insulation, which are particularly important in 2D van der Waals electronics. On the other hand, the controlled introduction in 2D h‐BN of multiple defects creates new properties and advanced functions. In this last case, only through a better understanding of the nature and function of defects, it is possible to develop advanced applications based on h‐BN heterostructures. Engineering of the heterojunctions, such as the design of bonding at the interfaces, also plays a primary role. Several applications are proposed for h‐BN heterostructures, mostly in sensing and photocatalysis, and some new perspectives worth further studies are opened. Finally, the current challenges and the rising opportunities for the future developments of next‐generation h‐BN heterostructures are discussed.

“…The as-synthesized BN nanostructures were always negatively charged intrinsically (Peng et al, 2013 ), which makes them the good h + carrier acceptor, and could be used to improve the h + /e − carrier separation in photocatalysis. As reported in literatures (Chen et al, 2014 ; Wang J. et al, 2015 ; Štengl et al, 2016 ; Liu et al, 2017 ; Li et al, 2018 ; Nasr et al, 2018 ), the combination of BN in the photocatalysts could effectively enhance the photocatalytic activities via improving the visible light absorption and reducing the recombination rate of hole/electron carriers. Therefore, the BN incorporated nanocomposite could be an alternative photocatalyst with enhanced visible light-responsive photocatalytic activities.…”

“…Due to the efficient carrier (h + /e − ) transfer from bismuth phosphate to the hBN, the recombination of h + -e − pairs was reduced, and more active •OH and

could be formed to enhance the photocatalytic efficiencies. Such effect in enhancing the carrier transfer rate and reducing the recombination rate of carrier pairs could also be found in the photocatalyst hBN/Ag 2 CO 3 (Wang J. et al, 2015 ).…”

Photocatalysts are essential to promote the highly efficient applications of solar energy in water splitting and/or the degradation of organic contaminations. Especially, the visible light-responsive photocatalysts could benefit with the cost-effective splitting or degradation due to the unlimited sunlight and the absence of expensive light emitter. In the photocatalysts, the charge transfer rates as well as the hole-electron recombination rate are two critical factors that determine the photocatalytic activity, which could also be affected by the dimension, defects, doping and morphologies controlled by the synthesis methods. Boron nitride (BN) is an ultrawide-bandgap semiconductor, and the combination of BN with the visible light-responsive photocatalysts has been found to be effective in enhancing the photocatalytic activities. Therefore, it should be meaningful to understand the BN incorporated photocatalytic composites in depth, including the synthetic approaches, the activity improving mechanisms and the versatile applications. In this review, we mainly focused on the assembly method of BN incorporated photocatalysts; the activity enhancing mechanism by introducing the BN in the photocatalytic composites as well as the properties and the applications. In the end, we gave a conclusion and an outlook for the BN incorporated photocatalytic composites.

“…All samples have a strong peak at 3300 cm –1 ; the peak is caused by the stretching vibration of surface −OH groups . As for the Ag 2 CO 3 –ZnO heterojunction, the absorption peaks displayed in 693, 833, 1394, and 1460 cm –1 due to the presence of CO 3 2– . In the process of photocatalysis, the surface −OH groups can combine with the photogenerated holes (h + ) to form ·OH, which can availably decompose dye molecules.…”

Dumbbell Ag2CO3–ZnO heterojunctions were synthesized for the first time via a simple in situ precipitation method. The as-prepared Ag2CO3–ZnO heterojunction showed high photocatalytic activity in the decomposition of methyl orange aqueous solution under simulated solar irradiation. The high improvement of photocatalytic activity compared to that of pure ZnO can be attributed to the formation of the Ag2CO3–ZnO heterojunction. Furthermore, the mechanism of photocatalytic activity was investigated in detail. The free radical trapping experiments indicated that the superoxide radical (·O2 –) was an important active species in the photocatalytic process. This paper provides a new prospect for the preparation of photocatalysts with high catalytic performance in the degradation of dye wastewater.
