Preparation and photocatalytic activity of continuous Ag-TiO2 fibers

摘要

The continuous Ag-TiO2 fibers were synthesized by the sol-gel method.The as-synthesized samples were characterized using XRD,SEM and XPS.The photocatalytic properties for degrading formaldehyde was primarily investigated.The results demonstrated that the as-synthesized Ag-TiO2 fibers all were crystal of anatase with about 20-40 tm in diameter.The continuous Ag-TiO2 fiber photocatalytic degradation rate of formaldehyde 98.4％,the degradation of formaldehyde was about 75％ for resusing 10 times.It would provide promising applications in cleaning indoor air.
