- Abstract:
- ZnSn(OH) 6 microl nanocubes with good dispersancy,uniform particle size distribution,and the average particle size for micro/nanoscale (100 ～200nm) were prepared by the hydrothermal method using (CH3COO)2Zn · 2H2O,NaOH and SnCl4 as reactants,and the acidificate the Zinc hydroxysta treatment,graphene oxide(GO) was prepared by a modified Hummers method.GO-ZnSn(OH)6 composite was prepared under the condition of low temperature,reduction graphene oxide (rGO) was obtained by photo induced reduction of GO under UV irradiation,and finally get rGO-ZnSn(OH)6 composite.The samples were characterized by the XRD,SEM,FT-IR,UV-Vis and PL to analyze the phase,microstructure and optical absorption properties,and the effect of different amounts of GO dopant on the photocatalytic property of rGO-ZnSn (OH) 6 composite was also evaluated using methylence blue as the degradation of material.The results showed that the mass fraction of GO was 2.0 (massfraction,％),the maximum degradation rate of the rGO-ZnSn(OH)6 composite was 93.2％,the degradation rate constant k =0.026min-1,which was 2 times and 4.3 times of the pure ZnSn(OH) 6,respectively.
