　　It seems logical that one of the best ways to fabricate the highly efficient photocatalysts may be to combine the 1-D nanomaterials with 2-D nanosheets.As a matter of fact,by taking advantage of the merits of 1-D AgVO3 nanostructures and 2-D ultra-thin g-C3N4 nanosheets,it is strongly desired that highly efficient photocatalysts are realized by hybridization of these components.However,until now,there are few reports focusing on the assembly of 2-D ultra-thin g-C3N4 nanosheets with 1-D AgVO3 nanostructures.As well known,the electronic structures of the choice photocatalysts for fabricating high efficient composite photocatalysts are crucial,thus,we first employ the density functional theory(DFT)calculations to investigate the density of states and band structures of AgVO3 and g-C3N4.Later,we develop a facile method to synthesize AgVO3/C3N4 composite photocatalysts via a facile one-step in-suit hydrothermal method.The detailed structural informations and photoreactivities of AgVO3/C3N4composite photocatalysts are investigated and compared with those of AgVO3 and C3N4.
