Sumario: | Multi-component two-dimensional (2D) hybrid sub-1 nm heterostructures could potentially possess many novel properties. Controlling the site-selective distribution of nanoparticles (NPs) at the edge of 2D hybrid nanomaterial substrates is desirable but it remains a great challenge. Herein, we realized for the first time the preparation of ternary hybrid CuO-phosphomolybdic acid-Ag sub-1 nm nanosheet heterostructures (CuO-PMA-Ag THSNHs), where the Ag NPs selectively distributed at the edge of 2D hybrid CuO-PMA sub-1 nm nanosheets (SNSs). And the obtained CuO-PMA-Ag THSNHs as the catalyst exhibited excellent catalytic activity in alkene epoxidation. Furthermore, molecular dynamics (MD) simulations demonstrated that the SNSs interact with Ag NPs to form stable nanoheterostructures. This work would pave the way for the synthesis and broader applications of multi-component 2D hybrid sub-1 nm heterostructures. |
