Abstract：

Perovskite　oxides　LaFe1-xCuxO3　(x　=　0-0.07)　was　prepared　by　a　conventional　citrate　complex　method.　The　structure,　shape,　particle　size,　the　photon　absorption　performance　and　surface　property　of　the　prepared　LaFe1-xCuxO3　(x　=　0-0.07)　were　investigated　by　using　XRD,　TEM,　UV-VIS　DRS,　XPS　and　PLS　techniques.　Perovskite　oxides　LaFeO3　prepared　is　a　kind　of　nano-sized　material.　Perovskite　oxides　LaFeO3　has　the　good　absorption　property　in　UV-visible　region,　and　a　series　of　Cu-doped　LaFeO3　have　more　respondence　to　the　visible　light.　Under　UV　light　irradiation,　H2　can　be　produced　by　photocatalytic　decomposing　of　water　over　the　prepared　LaFe1-xCuxO3　(x　=　0-0.07).　Doping　Cu2+　can　enhance　the　photocatalytic　activity　of　LaFeO3　to　a　certain　extent,　and　the　optimal　doping　molar　fraction　of　catalyst　is　0.05.
