| Abstract: | Cuprous oxide microsphere material was fabricated by electrochemical deposition using polystyrene particles as template. The samples are characterized by scanning electron microscope (SEM), X-ray diffraction, and UV–vis spectrophotometer. The SEM image shows the morphology and size of the microspheres, and the thickness of covered Cu2O layer is about 100 nm. Due to the unique microspherical structure, the surface area is larger, and the optical absorption is better in Cu2O microsphere material than in bulk Cu2O film, which makes the degradation of methylene blue faster and photoelectrocatalytic oxidation of glucose stronger on Cu2O microsphere material than on bulk Cu2O film under visible light illumination. The enhanced photo- and photoelectro-catalytic activity makes the Cu2O microsphere material more suitable for solar applications. |
