Synthesis of 2D Phosphorene: Current Status and Challenges

Abstract Phosphorene, a 2D(two‐dimensional) material, holds immense promise in various applications due to its unique properties. Here, a comprehensive overview of their recent synthesis progresses, with a specific focus on three phosphorene varieties: black phosphorene, blue phosphorene, and violet phosphorene is provided. Black phosphorene, given its versatile properties, is extensively studied, but the challenges persist in achieving scalable production with high quality and controllable thicknesses. The synthesis of blue phosphorene involves epitaxial methods but results in relatively small structures, limiting its practical applications. Notably, the successful synthesis of violet phosphorene remains limited, achieved only through mechanical and liquid‐phase exfoliation (LPE) methods. Despite significant progression in phosphorene synthesis, a critical need is emphasized for a cost‐effective and easily controllable method capable of efficiently managing the thickness of phosphorene. The challenges, such as scalability issues and the presence of impurities, highlight the complexity of phosphorene preparation methods. The review emphasizes the importance of continued scientific engagement to overcome these obstacles and advance the research topic. In essence, while phosphorene shows great potential, unlocking its full range of applications requires further research and innovation in synthesis methodologies.
