摘要: Abstract In this paper, Cu2O cubes with high photoelectrochemical activities were deposited on the surface of TiO2 nanotube arrays by ultrasound-assisted successive ionic layer adsorption and reaction (SILAR) method. The elemental composition morphology characterized XPS SEM. NTs/Cu2O showed excellent photoelectric conversion photoelectrocatalytic (PEC) removal organic dyes Cr(VI). results confirmed that SILAR deposition cycle greatly influenced visible light response PEC properties, (6) prepared 6 cycles optimal photocurrent (1.08 mA/cm2), photovoltage (−0.044 V/cm2), solar degradation efficiencies MO (77.62%), RhB (61.83%) MB (98.30%), reduction Cr(VI) (97.16%). photoelectrodes would show prospective applications in cells waste-water treatment due to significantly enhanced performance.
