Self-cleaning Finishing of Cotton Fabric with TiO2/Ag2S/rGO Composite

Titanium dioxide (TiO 2 ) could improve the self-cleaning performances of cotton fabric owing to its good photocatalytic performances. However, the fast recombination rate of the photogenerated electron-hole pairs and narrow photoresponse range of TiO 2 limit its wide application. In this work, Ag 2...

Description
Summary:Titanium dioxide (TiO 2 ) could improve the self-cleaning performances of cotton fabric owing to its good photocatalytic performances. However, the fast recombination rate of the photogenerated electron-hole pairs and narrow photoresponse range of TiO 2 limit its wide application. In this work, Ag 2 S and reduced graphene oxider (rGO) were compounded with TiO 2 , and the composite was loaded on the surface of cotton fabric by hydrothermal method to enhance the self-cleaning performance of cotton fabric. The close contact between Ag 2 S and TiO 2 increases the light response range. Then, rGO could effectively transfer photogenerated electrons, prolong the recombination time of carriers and improve the photocatalytic efficiency. The cotton fabric was characterized by XRD, SEM, Raman and fluorescence spectra. The photocatalytic degradation of methylene blue under visible light was studied. The results showed that TiO 2 /Ag 2 S/rGO adhered uniformly on the surface of cotton fabric and had good adhesion properties. In addition, under visible light irradiation, cotton fabric has excellent photocatalytic self-cleaning performance, washing resistance and rub resistance.
