Abstract:
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 MoS 2 /CdS heterostructures on carbon fiber (CF) cloth as a novel filter‐membrane‐shaped photocatalyst. With CF cloth as the substrate, the growth of MoS 2 nanosheets (thickness: ∼20 nm) and CdS nanoparticles (∼5 nm) have been achieved by using a hydrothermal‐chemical bath deposition two‐step route. CF/MoS 2 /CdS cloth shows a strong and wide photoabsorption accompanied by a small peak with an edge around 700 nm. Under visible‐light irradiation, CF/MoS 2 /CdS cloth (area: 4×4 cm 2 ) 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/MoS 2 /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/MoS 2 /CdS cloth has the capacity to be a recyclable photocatalyst with high efficiency for purifying the flowing wastewater.
