Semiconductor photocatalysis, a sustainable and renewable technology, is deemed to be a new path to resolve environmental pollution and energy shortage. The development of effective photocatalysts, especially the metal‐free photocatalysts, is a critical determinant of this technique. The recently emerged 2D material of black phosphorus with distinctive properties of tunable direct bandgap, ultrahigh charge mobility, fortified optical absorption, large specific surface area, and anisotropic structure has captured enormous attention since the first exfoliation of bulk black phosphorus into mono‐ or few layered phosphorene in 2014. In this article, the state‐of‐the‐art preparation methods are first summarized for bulk black phosphorus, phosphorene, and black phosphorus quantum dot and then the fundamental structure and electronic and optical properties are analyzed to evaluate its feasibility as a metal‐free photocatalyst. Various modifications on black phosphorus are also summarized to enhance its photocatalytic performance. Furthermore, the multifarious applications such as solar to energy conversion, organic removal, disinfection, nitrogen fixation, and photodynamic therapy are discussed and some of the future challenges and opportunities for black phosphorus research are proposed. This review reveals that the rising star of black phosphorus will be a multifunctional material in the postgraphene era.

“…[27][28][29][30][31][32] Recently, binary metal-free heterostructures combining BP and CN have shown promise in photocatalytic H 2 evolution and reactive oxygen species generation. [2][3][4][5][6][7][8][9][10][11] Owing to the unique optical and electrical properties, BP holds large promise in the fields of energy and catalysis. The preparation of these materials relies on the growth and exfoliation of BP crystals and the production cost and complexity increase inevitably.…”

A Low‐Cost Metal‐Free Photocatalyst Based on Black Phosphorus

et al. 2018

An efficient metal‐free photocatalyst composed of black phosphorus (BP) and graphitic carbon nitride (CN) is prepared on a large scale by ball milling. Using economical urea and red phosphorus (RP) as the raw materials, the estimated materials cost of BP/CN is 0.235 Euro per gram. The BP/CN heterostructure shows efficient charge separation and possesses abundant active sites, giving rise to excellent photocatalytic H2 evolution and rhodamine B (RhB) degradation efficiency. Without using a co‐catalyst, the metal‐free BP/CN emits H2 consistently at a rate as large as 786 µmol h−1 g−1 and RhB is decomposed in merely 25 min during visible‐light irradiation. The corresponding electron/hole transfer and catalytic mechanisms are analyzed and described. The efficient metal‐free catalyst is promising in visible‐light photocatalysis and the simple ball‐milling synthetic method can be readily scaled up.

“…Compared with bulk battery materials, 2D nanosheets (e. g., TiO 2 , V 2 O 5 , MoS 2 ) with ultrathin thickness and high surface-to-volume ratio usually exhibit boosted pseudocapacitive behavior resulting from the more exposed active sites, decreased diffusion barrier and distance of electrolyte ion, and alleviated volumetric strain. Since the application of 2D materials for LICs is still in the early stage, other newly developed 2D materials (e. g., phosphorene, [95] graphdiyne, [96] metal thiophosphate, [97] and layered double hydroxide nanosheets [98] ) also deserve to be investigated, and new 2D materials should be incessantly exploited to achieve high-performance LICs. Also, assembling 2D nanosheets into 3D porous architectures can improve the contact/interaction with electrolyte and facilitate the surface-driven pseudocapacitive charge storage.…”

ion capacitors (LICs) composed of a battery-type electrode and a capacitor-type electrode are highly competitive candidates for next-generation electrochemical energy storage devices, simultaneously achieving high energy and power densities. However, the present LICs are still hindered by the imbalance of electrode kinetics and capacity of anode and cathode. Recently, two-dimensional (2D) materials with unique structure and appealing properties have received extensive attentions for applications in LICs, with remarkable improvements from charge storage capacity to reaction kinetics. Herein, we review the recent advances in the applications of 2D materials for high-energy and high-power LICs. The key advantages and important roles of 2D materials are emphasized for the construction of LICs, including electrochemical active materials, ultrathin conductive and flexible supports for hybridization with other active materials, and 2D functional building blocks for assembling macroscopic hierarchical 3D frameworks. Finally, the challenges and prospects associated with the applications of 2D materials for high-performance LICs are discussed. especially power density and cycle life, nanostructured battery-type materials with high rate capability and long-term stability and optimized capacitor-type materials with high capacity should be continuously developed. [5][6]10] 2D materials are layered crystals with a thickness of single or few atoms, and often referred to nanosheets as well. [25] These ultrathin 2D nanosheets can be considered as elementary building blocks of the corresponding layered bulk materials and can be synthesized by exfoliation of the latter. Since graphene was discovered in 2004, [26] various 2D materials have been developed, including transition metal oxides (TMOs), transition metal dichalcogenides (TMDs), MXenes, polymers, phosphorene, boron nitride, etc. [27] The atomic-level thickness brings extraordinary physicochemical properties compared with the multilayer bulk materials, such as high SSA, excellent mechanical flexibility, tunable electronic structure, and enhanced electrochemical activities, making 2D materials highly attractive for electrochemical energy storage devices. [28] Also, the introduction of 2D materials has enabled great progress toward LICs with high energy density, high power density, and long cycle life.
