Preparation of Nanometer Sized Cuprous Oxide and Its Photocatalytic Performance Over Four Nitrophenol

摘要

Nanometer sized Cu_2O is synthesised by nucleation crystallization separation and redox methods, with NaBH_4 as reducing agent. It takes several researching methods, such as XRD, SEM, EDS and UV-vis, etc, to study the structure, composition and spectral features of the product. The results show that, comparing with traditional methods, the Cu_2O particles produced by nucleation crystallization separation and redox methods have following features: similar appearances, small particle size, and narrow distribution, etc. The photocatalytic experiment shows that, this kind of Cu_2O has excellent photocatalytic activity over four nitrophenol.
