摘要：
The development of efficient and recyclable photocatalysts with wide spectrum response has drawn much attention. Herein, we prepared TiO2/MoS2 heterostructures on carbon fibers (CFs) by a two-step hydrothermal method. CFs/TiO2/MoS2 exhibits a strong and wide absorption spectrum from ultraviolet to near-infrared region ( > 1200 nm). Under the irradiation of visible-light, CFs/TiO2/MoS2 could degrade 97.6% Rhodamine B (RhB) after 100 min, 94.2% Acid Orange 7 (AO7) or 93.4% tetracycline hydrochloride (TC) after 60 min, and 88.7% 4-chlorophenol (4-CP) after 180 min. Moreover, CFs/TiO2/MoS2 bundles can be further weaved into a cloth (area: 4 x 4 cm(2)). CFs/TiO2/MoS2 cloth as a working electrode exhibits significant photocurrent (7.53 x 10(-6) A/cm(2)) and enhanced photoelectrocatalytic efficiency (100% TC) comparing with only photocatalysis (90.7% TC) or electrocatalysis (47% TC). In particular, CFs/TiO2/MoS2 cloth shows excellent stability. Therefore, CFs/TiO2/MoS2 cloth has great potential to be used as flexible and weaveable photocatalyst/photoelectrode for degrading various pollutants.
