Electrochemical Exfoliation of Two‐Dimensional Phosphorene Sheets and its Energy Application

Recently, single or few‐layer phosphorene has attracted intense attention due to its exceptional physicochemical properties. To this end, mass production of high‐quality phosphorene nanosheets with specific functionalities represents a pivotal factor for the basic academic studies and practical applications. Among the current synthetic methods, electrochemical exfoliation of black phosphorous is one of the most hopeful ways for mass‐production of phosphorene sheets owing to the uncomplicated apparatus, low cost as well as significant efficiency. Especially, regulating the electrochemical parameters not only induces adjustable phosphorene characteristics but also enables them a promising candidate in energy applications. In this Review, a concise and crucial studies of the recent and most representative developments in this domain was introduced, including the relationship between exfoliation philosophy, internal mechanisms, processing techniques, and multiple applications of phosphorene. At the end, a summary discussion and future perspectives is also provided. This review presents concise and crucial studies of the recent and most representative developments in electrochemical exfoliation of two‐dimensional phosphorene sheets, including the relationship between exfoliation philosophy, internal mechanisms, processing techniques, and multiple applications of phosphorene. Finally, we also offer our insight into their future challenges and opportunities.
