Abstract

Cu₂O-TiO₂ composite films were prepared by combining narrow-band semiconductor material Cu₂O and TiO₂ with the electrochemical deposition and coating methods, and characterized with SEM, XRD, PL and UV-Vis DRS. The hydrogen production performance was tested with methanol solution as simulated wastewater. The effects of light source, TiO₂ loading, methanol solution concentration and pH on hydrogen production performance were investigated. The results show that the prepared Cu₂O-TiO₂ composite films can directly catalyze the hydrogen production of organic matter in water under sunlight. The higher the concentration of organic matter, the higher the hydrogen production. When the concentration of methanol is 50%, the hydrogen production is highest. In addition, the hydrogen production is higher when it is acidic.
