“…Thus, coupling g‐C 3 N 4 with other 2D semiconductors to construct a 2D/2D heterojunction would be a favorable choice to improve the photocatalytic activity by suppressing the recombination of charge carriers. To date, numerous semiconductors with 2D nanostructures have been developed to couple with g‐C 3 N 4 , such as metal oxides, [ 82 ] metal sulfides, [ 83 ] ternary chalcogenide, [ 80b,84 ] bismuth‐based compounds, [ 80a,85 ] layered double hydroxides, [ 86 ] black phosphorus, [ 47a,87 ] etc. For instance, Zhang et al.…”

“…Besides, similar ultrasonic dispersion process was also used to construct a 2D/2D heterojunction between layered BiVO 4 and g‐C 3 N 4 nanosheets. [ 85a ] In another case, leaf‐like ZnIn 2 S 4 nanosheets uniformly in situ grew on the surfaces of g‐C 3 N 4 nanosheet via a simple one‐step surfactant‐assisted solvothermal method. [ 84 ] With face‐to‐face contact, a lot of unique high‐speed charge transfer nanochannels formed, which greatly shortened the charge transfer time and enhanced the charge separation efficiency.…”

Semiconductor photocatalysis is currently attracting tremendous attention as it holds great potential to address the issues of energy shortage and environmental pollution. 2D materials are excellent candidates for photocatalysis owing to their attractive structural and electronic properties. However, practical applications of 2D materials are still hindered due to limitations, such as fast electron–hole recombination and poor redox ability, both of which lead to low efficiency of photocatalytic reactions. Constructing a heterojunction is the most widely used strategy to solve these problems. In particular, heterojunctions composed of 2D materials interfaced with other semiconductors of different dimensionalities can integrate the respective advantages and mitigate the drawbacks of each component. Hence, this review focuses on the recent developments in the rational design of 2D material‐based heterojunction photocatalysts with different configurations. The synthetic strategies, physicochemical properties, component functions, photocatalytic mechanisms, and applications of these heterojunctions are systematically summarized. Emphasis is placed on correlations between photocatalytic performance and heterojunction configuration. Finally, the ongoing challenges and potential directions for future development of 2D material‐based heterojunction photocatalysts are also proposed.

“…Under visible light irradiation, the Z-scheme Bi 3 O 4 Cl/g-C 3 N 4 2D/2D heterojunctions exhibited outstanding photocatalytic activity for removing the various water contaminants. Besides these, some other types of 2D bismuth-contained semiconductors were also reported to couple with g-C 3 N 4 to construct 2D/2D heterojunctions for environmental remediation, such as C 3 N 4 /Bi 20 TiO 32 [29], BiOIO 3 /g-C 3 N 4 [109], Bi 2 O 2 CO 3 /g-C 3 N 4 [99], BiVO 4 /g-C 3 N 4 [120]. It can be found that the above discussed g-C 3 N 4 based 2D/2D photocatalysts contained at least one metal element, which would raise economic cost concern of large-scale production.…”

Two-dimensional/two-dimensional (2D/2D) hybrid nanomaterials have triggered extensive research in the photocatalytic field. The construction of emerging 2D/2D heterostructures can generate many intriguing advantages in exploring high-performance photocatalysts, mainly including preferable dimensionality design allowing large contact interface area, integrated merits of each 2D component and rapid charge separation by the heterojunction effect. Herein, we provide a comprehensive review of the recent progress on the fundamental aspects, general synthesis strategies (in situ growth and ex situ assembly) of 2D/2D heterostructured photocatalysts and highlight their applications in the fields of hydrogen evolution, CO 2 reduction and removal of pollutants. Furthermore, the perspectives on the remaining challenges and future opportunities regarding the development of 2D/2D heterostructure photocatalysts are also presented.

Photoelectrochemical (PEC) water splitting is a rational and effective way that imitates natural photosynthesis for direct conversion of solar energy into clean hydrogen fuels. Developing highly efficient photoanodes to enhance the kinetics of the rate‐determining oxygen evolution reaction is generally regarded as the key to achieve artificial photosynthesis. Recently, bismuth vanadate (BiVO4) has emerged as a promising photoanode material for PEC applications. In this Review, recent progress in designing BiVO4‐based photoanodes is presented and summarized, including morphological control, heteroatom/defect doping, hetero‐/homo‐junction fabrication and co‐catalyst deposition. In addition, typical unbiased tandem devices of photoanode/photocathode and photovoltaic/photoanode systems using BiVO4 as the front‐absorber photoanodes are reviewed. Finally, a future outlook is provided to highlight the issues to be addressed for commercial applications of PEC devices for solar water splitting.
