【Abstract】 TiO₂/Ni-Fe hydrotalcite composite photoelectrode was prepared by hydrothermal synthesis and electrodeposition,and its structure,morphology,light absorption and photoelectric properties are characterized by XRD,SEM,UV-vis DRS and electrochemical measurement. The photoelectricity catalytic performance of this composite photoelectrode is studied by using dye as model system. The experiment involves many practical links,such as the preparation,characterization and performance evaluation of photoelectric materials,and also covers the knowledge points of chemistry,materials,environment,photoelectrochemistry and other disciplines. Through this experiment,students’ practical ability and interest in scientific research can be improved,their consciousness of scientific research innovation can be enhanced,and their comprehensive practical ability can be cultivated.更多还原
