“…Additionally, the surface modification of BP can also be realized by bonding other materials with BP to form heterostructure. Li et al [ 117 ] proposed to combine BP with Ti 3 C 2 to construct 2D BP/Ti 3 C 2 heterostructure. It was found that compared with the naked BP, the BP/Ti 3 C 2 appeared the red-shifts of Raman peaks, illustrating that new chemical bond was formed [ 118 ].…”

HIGHLIGHTS • The preparation methods, basic structure, and properties as well as environmental instability and passivation techniques of twodimensional black phosphorus are systematically summarized and analyzed. • The application of anode materials based on two-dimensional black phosphorus in lithium-ion batteries in recent years is wholly reviewed. ABSTRACT Two-dimensional black phosphorus (2D BP), an emerging material, has aroused tremendous interest once discovered. This is due to the fact that it integrates unprecedented properties of other 2D materials, such as tunable bandgap structures, outstanding electrochemical properties, anisotropic mechanical, thermodynamic, and photoelectric properties, making it of great research value in many fields. The emergence of 2D BP has greatly promoted the development of electrochemical energy storage devices, especially lithium-ion batteries. However, in the application of 2D BP, there are still some problems to be solved urgently, such as the difficulty in the synthesis of large-scale high-quality phosphorene, poor environmental stability, and the volume expansion as electrode materials. Herein, according to the latest research progress of 2D BP in the field of energy storage, we systematically summarize and compare the preparation methods of phosphorene and discuss the basic structure and properties of BP, especially the environmental instability and passivation techniques. In particular, the practical application and challenges of 2D BP as anode material for lithium-ion batteries are analyzed in detail. Finally, some personal perspectives on the future development and challenges of BP are presented.

“…For example, Ti 3 C 2 T x has poor oxygen resistance and is prone to be oxidized into TiO 2 in oxygen-dissolved or even anaerobic solution by the trace amount of the oxygen or surface-attached oxygen-containing groups. [18,59,63,135,187,189,[191][192][193] In addition to the possible surface oxidation of MXenes during the fabrication of MXenes-based composites, [194] the reaction conditions also likely induce the MXenes oxidation. [33,[54][55][56][57] It has been reported that multilayered Ti 3 C 2 T x can slowly react with dissolved oxygen to form titanium hydroxide and/or TiO 2 on its surface, [33] and the UV light could accelerate the oxidation process of Ti 3 C 2 T x .…”

MXenes are becoming a worthy contender for boosting the efficacy of semiconductor photocatalysts because of their rich surface and electronic properties, which is exemplified to be a dynamic yet open‐ended exploration of the materials space. Herein, the promise that MXenes hold for photocatalytic applications is elucidated by presenting the various roles of MXenes in the preparation of composite photocatalysts and enhancing their activity and stability. A specific focus is put on the key issues that should be taken into account when utilizing the specific function of MXenes and the strategies to deliver the great potential of MXenes into better play. The discussion is based on different aspects closely related to the flexible surface and electronic features of MXenes, including their morphology control, stability issue, and electronic structure mutability with the purpose to present an objective and comprehensive scenario of MXenes for photocatalysis. Finally, some noteworthy research directions for the future development of MXenes‐based photocatalytic systems are outlined and prospected. This review is expected to provide a useful scaffold for the rational design and synthesis of efficient and stable MXenes‐based photocatalysts by objectively understanding and taming the functional vitality of MXenes.

“…Phosphorene has also been studied for its electrocatalytic properties, which research shows outperforms ruthenium (iv) oxide and Co 3 O 4 /N-graphene [ 41 ]. Currently, while a large bulk of experimental research efforts has focused towards producing air stable phosphorene [ 40 , 41 , 42 , 43 ], there is limited information on the incorporation of phosphorene in membranes as well as a thorough understanding of its physicochemical properties when utilized as a membrane additive In a previous study [ 6 ], the photocatalytic properties of phosphorene-based membranes were examined; on the other hand, in this study, the effects of phosphorene on the morphologic structure of the polymeric blend along with the evolution of the modifications were investigated. Furthermore, we discuss its stability under several pH environments as well as study biologic effects of phosphorene-based membrane permeates on a nematode.…”

Nanohybrid Membrane Synthesis with Phosphorene Nanoparticles: A Study of the Addition, Stability and Toxicity

et al. 2020

Phosphorene is a promising candidate as a membrane material additive because of its inherent photocatalytic properties and electrical conductance which can help reduce fouling and improve membrane properties. The main objective of this study was to characterize structural and morphologic changes arising from the addition of phosphorene to polymeric membranes. Here, phosphorene was physically incorporated into a blend of polysulfone (PSf) and sulfonated poly ether ether ketone (SPEEK) doping solution. Protein and dye rejection studies were carried out to determine the permeability and selectivity of the membranes. Since loss of material additives during filtration processes is a challenge, the stability of phosphorene nanoparticles in different environments was also examined. Furthermore, given that phosphorene is a new material, toxicity studies with a model nematode, Caenorhabditis elegans, were carried out to provide insight into the biocompatibility and safety of phosphorene. Results showed that membranes modified with phosphorene displayed a higher protein rejection, but lower flux values. Phosphorene also led to a 70% reduction in dye fouling after filtration. Additionally, data showed that phosphorene loss was negligible within the membrane matrix irrespective of the pH environment. Phosphorene caused toxicity to nematodes in a free form, while no toxicity was observed for membrane permeates.
