As a low-budget, facile-availability and eco-friendly substrate material, cotton fabric after hydrophobic modification has been applied to sewage purification. While, a single superhydrophobic function is unable to decompose toxic water-soluble organic dye. In this paper, pathways are propounded for the simultaneous achievement of the removal of insoluble spilling oil and organic dye contaminants. Particularly, the hydrophobic ZnSnO3 after stearic acid modification and Bi2MoO6 catalysts are introduced into the cotton fabric substrate through solution dip-coating. The durability of the prepared fabric suffers from the acid-base corrosion, thermal treatment and mechanical wear, meanwhile, it still exhibits remarkable water repellent (WCA > 150°) property. Furthermore, the remarkable photocatalytic activity makes it possible for reusable degradation and the primary active species, namely the holes, to be verified by the radicals-capturing experiment.
