“…Compared with amorphous RP, both of them could enhance the degradation rate by narrowing the band gap of RP, improving crystallinity and specific surface area, but they were not ideal. 119 Table 4 shows that another means for enhancing the photocatalytic efficiency is to construct heterojunction photocatalysts by combining RP with other semiconductor materials, which not only improves the light absorption but also promotes the separation and transfer of photogenerated carriers. For example, Yu and Shen et al constructed the RP/BP heterojunction using amorphous RP as the precursor via simple mechanical ball milling.…”

Phosphorus is an important non‐metal element with many allotropes and tunable electronic properties. As one of the most important allotropes of phosphorus, two‐dimensional (2D) black phosphorus (BP) possesses many extraordinary properties, such as high charge carrier mobility with high on/off ratio, thickness‐dependent direct bandgap varying from 0.3 to 2 eV, and anisotropic electrical, optical and thermal properties. Inspiring by the success of 2D BP, other 2D phosphorus allotropes with intriguing properties for next‐generation electronic and optoelectronic devices have also attracted much attention. However, large‐scale growth of high‐quality 2D single/few‐layer phosphorus remains a great challenge. In this review, we highlight recent progress achieved on 2D phosphorus, with special focus on the epitaxial growth of 2D BP films, blue phosphorus (BlueP) monolayers as well as phosphorus‐metal porous networks. The remaining challenges and future perspectives on the development of monolayer phosphorus or phosphorus‐metal alloys are also provided.

“…During the growth process, well-designed morphologies of RP can be fabricated depending on the architecture of the substrate photocatalysts. This approach could indeed expand the light absorption, inhibit the charge recombination, and promote charge transfer by building the hybrid photocatalysts. − However, to ensure the sublimation of commercial RP, the temperature is usually above 500 °C, and a vacuum environment is necessary. These harsh requirements would restrict the general application of this strategy.…”

Developing active photocatalysts using wide-spectrum light is crucial to promote the application of photocatalytic water splitting. Elemental red phosphorus (RP) has attracted much attention as a potential nonmetal photocatalyst owing to its low cost, earth abundance, and narrow bandgap. Herein, RP nanosheets were synthesized and tightly combined with carbon nitride (CN) framework nanosheets to form RP/CN van der Waals (vdW) heterostructure. CN nanosheets could act as a substrate to generate RP nanosheets through a “confinement effect”. This hybrid photocatalyst could utilize the incident light with the wavelength longer than 620 nm for pure water splitting, with hydrogen production activity of 367.0 μmol h–1g–1 under full arc illustration and 239.8 μmol h–1g–1 under visible light irradiation. The improved photocatalytic property was ascribed to the wide light absorption and intimate electronic coupling between 2D RP and 2D CN for accelerated charge transfer. Instead of O2, water was oxidized into H2O2 via a two-electron pathway, which could avoid the potential explosion by producing H2 and O2 simultaneously. This work proved the great potential of RP-based vdW heterostructures for solar-driven water splitting.
