“…The emergence of new energy levels in Co‐doped In 2 S 3 can be attributed to the splitting of Co 3d state, which promotes the excitation of VB electrons through the d → d internal transition of Co ions in tetrahedral coordination. In the case of in situ surface doping modification of atomically thin 2D g‐C 3 N 4 by Se, [ 155 ] UV–vis DRS has proved that the absorption edge of g‐C 3 N 4 can be extended from 416 to 584 nm after Se doping (Figure 5H). Accordingly, the bandgap is reduced from 3.06 to 2.73 eV after the Se decoration, as evidenced by the Tauc diagram (Figure 5I).…”

2D materials show many particular properties, such as high surface‐to‐volume ratio, high anisotropic degree, and adjustable chemical functionality. These unique properties in 2D materials have sparked immense interest due to their applications in photocatalytic systems, resulting in significantly enhanced light capture, charge‐transfer kinetics, and surface reaction. Herein, the research progress in 2D photocatalysts based on varied compositions and functions, followed by specific surface modification strategies, is introduced. Fundamental principles focusing on light harvesting, charge separation, and molecular adsorption/activation in the 2D‐material‐based photocatalytic system are systemically explored. The examples described here detail the use of 2D materials in various photocatalytic energy‐conversion systems, including water splitting, carbon dioxide reduction, nitrogen fixation, hydrogen peroxide production, and organic synthesis. Finally, by elaborating the challenges and possible solutions for developing these 2D materials, the review is expected to provide some inspiration for the future research of 2D materials used on efficient photocatalytic energy conversions.

“…In 2019, Mo et al [35] proposed a Z-scheme system containing two-dimensional (2D) MnO 2 /monolayer graphitic carbon nitride with defective Mn 3+ active sites for H 2 production, while TEOA was used as a sacrificial agent. After Mn 3+ /Mn 4+ redox couples were introduced, these defective Mn 3+ active sites could promote H 2 O adsorption and boost the charge separation and transfer at the interface, resulting in a H 2 production rate of 28.0 mmol•g -1 •h -1 and an AQE of 23.33% at λ = 420 nm.…”

The development of green and renewable energy is becoming increasingly more important in reducing environmental pollution and controlling CO 2 discharge. Photocatalysis can be utilized to directly convert solar energy into chemical energy to achieve both the conversion and storage of solar energy. On this basis, photocatalysis is considered to be a prospective technology to resolve the current issues of energy supply and environmental pollution. Recently, several significant achievements in semiconductor-based photocatalytic renewable energy production have been reported. This review presents the recent advances in photocatalytic renewable energy production over the last three years by summarizing the typical and significant semiconductorbased and semiconductor-like photocatalysts for H 2 production, CO 2 conversion and H 2 O 2 production. These reactions demonstrate how the basic principles of photocatalysis can be exploited for renewable energy production. Finally, we conclude our review of photocatalytic renewable energy production and provide an outlook for future related research.
