Abstract：

A　perovskite-like　compound　La2CuO4-based　material,　a　well-known　high-temperature　superconductor,　was　studied　as　a　photocatalyst.　H2　was　produced　over　La2CuO4　from　aqueous　solutions　containing　methanol　as　a　sacrificial　reagent　under　high-pressure　Hg　lamp　irradiation.　The　photocatalytic　activity　of　La2CuO4　is　superior　to　that　of　the　commercial　anatase　TiO2,　and　can　be　greatly　improved　by　loading　with　Cu2O.　Photoelectrochemical　measurements　revealed　that　the　conduction　band　minimum　of　the　La　2CuO4　photocatalysts　is　thermodynamically　feasible　for　the　reduction　reaction　of　water　and　Cu2O　efficiently　increase　the　electron-hole　separation　on　La2CuO4　under　photon　irradiation　to　account　for　its　higher　photocatalytic　activity.　©　2013　Elsevier　B.V.
