Photocatalytic Activity of Cotton Fabric Modified by Manganese Dioxide Thin-Layer Using an Electrochemical Coating Method

Electrochemical coating of nanostructures is a rapid, low-cost and useful method to prepare a high-stable and unique thin-layer on the surface. The current paper present the preparation of a cotton fabric with photocatalytic properties activity by a two-step process including spin coating of graphite on the surface of cotton fabric, and electrochemical coating of manganese dioxide nanoparticles on the modified cotton fabric. Electrodeposition was carried out using a potentiostatic method at a constant current of ۲ A for ۱۲۰۰ s. FESEM image of the modified cotton fabric indicated a unique thin-layer of spherical manganese dioxide nanoparticles on the surface. Also, the photocatalytic degradation of methylene blue on the surface of the modified cotton fabric reached to ۸۴.۱ % after ۱۲۰ min. The prepared cotton fabric with photocatalytic properties activity can be used in various applications due to its good photocatalytic activity.
