Preparation and photocatalytic properties on ZnO/TiO2 nanotubes
In order to study on the effect of the content of Zn to phase morphology and photocatalytic performance of ZnO/TiO2 composite material,we prepare ZnO particle finishing with surface chemistry and make tubular TiO2 with hydrothermal.Using characterization methods like XRD,SEM,TEM to explore how various conditions such as different incineration temperature,atomic ratio,etc can interfere with morphology,structure and photocatalytic performance of composite.In this experiment,the surface of TiO2 nanotubes combusted under the temperature of 673K for 2h are smooth;Zn:TiO2=1:4 to achieve uniformly and firmly distributed nano composite particles which grain size is 11nm on the surface of TiO2 nanotubes,including 2-3nm ZnO particles on tubes; 0.1mol/L sodium hydrate-ethanol solution as precipitant to obtain ZnO/tubular TiO2 composite materials which are highly dispersed and deposited on the surface of tube-shaped TiO2; Zn:Ti=1:4 reach the best catalytic result.
