Ye, M.Zhao, Z.Hu, Z.Liu, L.Ji, H.Shen, Z.Ma, T.2017-08-092017-08-092017Angewandte Chemie International Edition, 2017; 56(29):8407-84111433-78511521-3773http://hdl.handle.net/2440/1066820D/2D heterojunctions, especially quantum dots (QDs)/nanosheets (NSs) have attracted significant attention for use of photoexcited electrons/holes due to their high charge mobility. Herein, unprecedent heterojunctions of vanadate (AgVO₃ , BiVO₄ , InVO₄ and CuV₂ O₆ ) QDs/graphitic carbon nitride (g-C₃ N₄ ) NSs exhibiting multiple unique advances beyond traditional 0D/2D composites have been developed. The photoactive contribution, up-conversion absorption, and nitrogen coordinating sites of g-C₃ N₄ NSs, highly dispersed vanadate nanocrystals, as well as the strong coupling and band alignment between them lead to superior visible-light-driven photoelectrochemical (PEC) and photocatalytic performance, competing with the best reported photocatalysts. This work is expected to provide a new concept to construct multifunctional 0D/2D nanocomposites for a large variety of opto-electronic applications, not limited in photocatalysis.en© 2017 Wiley-VCH Verlag GmbH & Co.
