| 英文摘要 | With industrial advancement and population growth, the freshwater shortage crisis has become a significant challenge, leaving nearly one billion people worldwide in urgent need of clean water. Previous investigations have shown that among the known 2D (two-dimensional) carbon-based desalination membranes, only graphdiyne possesses a periodic and appropriately sized pore structure, which results in near-perfect salt rejection and water flux. However, graphdiyne still requires improvement to address fouling and biofouling issues in complex marine environments. Here, an easily synthesizable desalination membrane, Ag-GDY (Ag-doped graphdiyne), with ultra-high water flux and remarkable photodegradation properties, was identified and validated through high-throughput screening and molecular dynamics simulations. The results demonstrate that Ag-GDY exhibits exceptional desalination properties, achieving an unprecedentedly high water flux of 750 L.m(-2).day(-1).MPa-1, which exceeds that of all currently utilized 2D carbon-based desalination membranes. Additionally, Ag-GDY demonstrates a narrower band gap (0.46 eV) and an unexpectedly flat band structure, making it the best candidate for optical response within the visible light range, with an absorption coefficient as high as 54.89 x 10(3) cm(-1). This study represents a pioneering attempt to incorporate first-principles calculations into the research of new desalination membranes, which provides experimental researchers with additional avenues for exploration. |
