Wet-chemical Synthesis of Elemental 2D Materials

Chem Asian J. 2024 Mar 12:e202301152. doi: 10.1002/asia.202301152. Online ahead of print.ABSTRACTWet-chemical synthesis refers to the bottom-up chemical synthesis in solution, which is among the most popular synthetic approaches towards functional two-dimensional (2D) materials. It offers several advantages including cost-effectiveness, high yields, and precious control over the production process. As an emerging family of 2D materials, elemental 2D materials (Xenes) have shown great potential in various applications such as electronics, catalysts, biochemistry, and sensing technologies due to their exceptional/exotic properties such as large surface area, tunable band gap, and high carrier mobility. In this review, we provide a comprehensive overview of the current state-of-the-art in wet-chemical synthesis of Xenes including tellurene, bismuthene, antimonene, phosphorene, and arsenene. The current solvent compositions and process parameters utilized in wet-chemical synthesis and their effects on the thickness and stability of the resulting Xenes are also presented. Key factors considered involves ligands, precursors, surfactants, reaction time, and temperature. Finally, we highlight recent advances and existing challenges in the current application of wet-chemical synthesis for Xenes production and provide perspectives on future improvement.PMID:38469659 | DOI:10.1002/asia.202301152
