  Polyoxometalate Clusters Confined in Reduced Graphene …

  2024617 · Abstract Efficient 2D membranes play a critical role in water purification and desalination. However, most 2D membranes, such as graphene oxide (GO) membranes, tend to swell or disintegrate in liquid, making precise ionic sieving a tough challenge. Herein, the fabrication of the polyoxometalate clusters (PW 12) intercalated …
