Bene?ting from this unique structure with synergistic effect of inner electronic ?eld and Schokkty barrier, the as-fabricated Au/Cu2O Schottky contact heterostructures exhibit enhanced photocatalytic activity to pure Cu2O microcubes in dye decomposition and water splitting under visible light illumination. The photodegradation rate of the as-constructed Au/Cu2O Schottky contact heterostructures for methyl orange (MO) is 1.2 times higher than that of pure Cu2O microcubes under visible light irradiation for 90 min. The photocurrent density of the as-prepared Au/Cu2O heterostructures electrode reaches up to 30 mA cmà2, which is 3 times higher than that (10 mA cmà2) of pure Cu2O microcube electrode at 1.23 V vs RHE. The enhanced photocatalytic activity of the as-constructed Au/ Cu2O Schottky contact heterostructures i
