The development of effective, visible-light-drivable and reusable photocatalysts has drawn great attention for purifying the flowing wastewater. Herein, we have designed and prepared MoS2/CdS heterostructures on carbon fiber (CF) cloth as a novel filter-membrane-shaped photocatalyst. With CF cloth as the substrate, the growth of MoS2 nanosheets (thickness: ~20 nm) and CdS nanoparticles (~5 nm) have been achieved by using a hydrothermal-chemical bath deposition two-step route. CF/MoS2/CdS cloth shows a strong and wide photoabsorption accompanied by a small peak with an edge around 700 nm. Under visible-light irradiation, CF/MoS2/CdS cloth (area: 4× 4 cm2) can expeditiously remove 97.3% rhodamine B, 55.6% tetracycline hydrochloride and 68.4% hexavalent chromium after 100 min, and 97.3% methylene blue after 70 min. In particular, when CF/MoS2/CdS cloth (diameter: ~10 cm) is used as a filter-membrane to photocatalytically degrade the flowing wastewater (10 mg L-1 RhB, rate: ~1 L h-1), 92.6% RhB can be eliminated in eight grading pools. Therefore, CF/MoS2/CdS cloth has the capacity to be a recyclable photocatalyst with high efficiency for purifying the flowing wastewater.
