Preparation of composite catalyst ag-ticarbon fiber and photocatalytic degradation of Rhodamine B
In this paper,a novel agnst-supported carbon fiber photocatalytic material was prepared by sol-gel method using titanium acetate,silver nitrate and carbon titanium dioxide as raw materials.The microstructure and morphology were observed by XRD and SEM.It was found that the composite photocatalytic material had good crystalline performance and higher catalytic activity due to the addition of Ag.The effect of photocatalyst on the degradation of Rhodamine B solution was investigated.It was found that when the amount of photocatalyst reached 0.30g·L-1 and the concentration of Rhodamine B solution was 6mg·L-1,the degradation activity was the highest in the case of the composite photocatalyst with Ag/TiO2=2∶1,and it could reach more than 88%,which could provide a technical support for the treatment of dye wastewater.
