Preparation of Hydrolyzed ZnO/Zn Hybrid Nanostructure with Zn Nanopaticle and its Photocatalytic Performance
Zn nanopaticles scaled between 30-100 nm was prepared by the roller vibration milling in dry mode at room temperature, and the hydrolyzed ZnO/Zn hybrid nanostructure was attained from hydrolyzation while Zn nanopaticles contacted with water vapour in normal atmospheric pressure. Energy dispersive spectrometer (EDS) showed that the hydrolyzed production was made up of Zn and ZnO, and Transmission Electron Microscope (TEM) images showed that the hydrolyzed ZnO/Zn hybrid nanostructure had great dispersivity featuring nano-rods intermixed with nano-flakes. It was proved to have great photocatalytic performance in methyl orange (MO) degradation. Using it as catalyst, exposed 10mg/L MO solution to a 20W UV source light with a distance of 40 cm, the degradation rate will reach to over 80% in 60 min.
