AB  - A stable MoS(2) nanosheets@TiO(2) NTAs composite was prepared via a simple 
      hydrothermal process. Few-layer MoS(2) nanosheets distributed on the TiO(2) 
      nanotube top surface and the inner walls rather than filling in the tubes, 
      allowing abundant tubular channels open to environment and benefiting for 
      efficient mass transport. Photocatalytic (PE) and photoelectrocatalytic (PEC) 
      performance of the composite were evaluated on Cr(VI) reduction, with variable 
      low molecule weight organic acids (LOAs) added as sacrificial electron donor to 
      form a charge-transfer-complex (CTC) between LOAs and TiO(2)/MoS(2), which is 
      sensitive to the visible light illumination and could induce the photo-reduction 
      of Cr(VI) and photo-oxidation of LOAs. The overall trend of Cr(VI) PEC rates are 
      in the order as: L(+)-Tartaric acid>oxalic acid>citric acid>malic acid>amber 
      acid, which is 103.9>62.5>31.2>21.6>2.5mg/Lmin(-1)cm(-2), respectively. The 
      improved catalytic performance and excellent stability of the composite can be 
      attributed to the abundant active adsorption and reaction sites on MoS(2) 
      nanosheets and the formation of a heterojunction between TiO(2) and MoS(2). 
      Moreover, the appropriate application of LOAs and voltage also have a great 
      contribution to the utilization of sunlight and efficient separation of 
      photogenerated carriers.
