Abstract: A hybrid photoactive heterojunction including a copper vanadate, Cu2V2O7 (CVO) and a zinc vanadate, Zn2V2O6 (ZVO). Particles of the ZVO are dispersed in particles of the CVO to form the hybrid photoactive heterojunction. The hybrid photoactive heterojunction in the form of a photoactive film includes a substrate which is at least partially coated with the hybrid photoactive heterojunction. A method of photodegrading a dye includes contacting the photoactive film and the dye in a solution and exposing the solution to light. A method of photoelectrochemically oxidizing water includes contacting the photoactive film with water in a solution and exposing the solution to light.

Abstract: A method of forming a one-dimensional nanoarray of In2O3 nanowires on indium foil is disclosed. The nanowires of In2O3 have diameters of 30 nm-50 nm and lengths of 100 nm-200 nm, and are attached to and substantially perpendicular to the surface of the indium foil. The In2O3 nanoarray may have a nanowire density of 200-300 nanowires per μm2 indium foil and a band gap energy of 2.63-3.63 eV. The In2O3 nanoarray may be formed by anodization of indium foil in an electrochemical cell subjected to a voltage of 15-25 V at room temperature.
