| Abstract: | With konjaku flour as soft template,spherical Se nanoparticles were prepared by chemical reduction method.The influence of the factors such as different reductants,the amount of konjaku flour and temperature on Se nanoparticles was studied.The structure and morphology of the products were characterized by SEM and XRD.The uniform stable selenium nanospheres were obtained under conditions of 3.0×10-3(mass fraction) konjaku flour,n(Vc)∶n(Na2SeO3)=3∶1 and 1.5 h after the initiation of the reaction at 40 ℃.The average particle size of selenium was about 60~150 nm. |
