摘　　要：The insulator Na2Ta4O11 has been considered as a potential photocatalyst.However,little attention has been given to the synthesis of Na2Ta4O11 nanoparticles,let alone the growth of two-dimensional(2D)layered Na2Ta4O11 flake,which may bring innovative properties and promising applications.Here,the 2D thin-layer Na2Ta4O11 flake was first produced by chemical vapor deposition(CVD)method,with the smallest thickness reported currently.We have also synthesized 2D Na2Ta4O11 flake over 100μm,which was the largest value over the 2D level reported to date.Our work proposed novel strategies to synthesize other 2D metal oxide material and endow the Na2Ta4O11 more properties and applications.
